Redis Labs Modules Forked » Linux Magazine


As expected, developers from the desktop projects Fedora and Debian have forked the modules that database vendor Redis Labs put under the Commons Clause.

The Commons Clause is an extra license rider that prohibits the user from “selling” the software, and “selling” is defined to include selling services such as hosting and consulting. According to Redis Labs and the creators of the Commons Clause, the rider was created to prevent huge hosting companies like Amazon from using the code without contributing to the project. Unfortunately, the license also has the effect of making the Redis Labs modules incompatible with the open source licenses used with Linux and other FOSS projects.

To fix the problem, Debian and Fedora came together to fork these modules. Nathan Scott, Principal Software Engineer at Red Hat, wrote on a Google Group, “…we have begun collaborating on a set of module repositories forked from prior to the license change. We will maintain changes to these modules under their original open source licenses, applying only free and open fixes and updates.”

It was an expected move. When license changes are made to any open source project, often some open source community jumps in and forks the project to keep a version fully compatible with the earlier open source license. The fork means commercial vendors like Amazon will still be able to use these modules without contributing anything to Redis Labs or the newly forked project. However, not all forks are successful. It’s not the license that matters. What matters is the expertise of the developers who write and maintain the codebase. Google once forked Linux for Android, but eventually ended up merging with the mainline kernel.

In a previous interview, Redis Labs told me that they were not sure whether adding the Commons Clause to these licenses would work or not; they already tried the Affero GPL (AGPL)  license, which is also designed to address the so-called application service provider loophole that allows cloud vendors to avoid contributing back their changes, but the move to the AGPL didn’t help them get vendors like Amazon to contribute.

Redis Labs added the Commons Clause to only those modules that their staff wrote; there is no change to the modules written by external parties.

Debian Celebrates its Birthday » Linux Magazine


The Debian GNU/Linux project celebrated its 25th birthday on August 16, 2018. Debian was created in 1993 by Ian Murdock. The name of the project came from the first three letters of his then girlfriend Debra and his own name – Deb Ian.

In the Debian manifesto, Murdock wrote, “Debian Linux is a brand-new kind of Linux distribution. Rather than being developed by one isolated individual or group, as other distributions of Linux have been developed in the past, Debian is being developed openly in the spirit of Linux and GNU. The primary purpose of the Debian project is to finally create a distribution that lives up to the Linux name. Debian is being carefully and conscientiously put together and will be maintained and supported with similar care.”

Debian has evolved to become one of the most popular distributions. It’s stable branch dominates the Linux powered web hosting services. The popularity of Debian also lead to the entire generation of Debian-based distributions, including Ubuntu and Knoppix.

Debian has three releases: stable, testing, and unstable. Stable is meant to be used on servers and by users who don’t want their systems to change frequently. Stable has packages that are very well tested and as a result they could be old.

Testing has packages that are not part of stable yet but are in the queue. Most Debian-based distributions, such as Ubuntu, are based on testing. It’s also suitable for desktop on home PCs.

Debian Unstable is the place where all development happens; it’s really bleeding edge and is meant only for developers.

The current version of Debian is 9 and its code name is Stretch. Each version of Debian is code-named after a character from the movie Toy Story. The unstable branch is code-named Sid, because Sid is the character that breaks everything.

What Microsoft’s GitHub Deal Promises to Programmers | Business


By Jack M. Germain

Jun 11, 2018 11:00 AM PT

Microsoft sent tremors through the open source world last week, when it announced that it would acquire the popular developer platform
GitHub for US$7.5 billion in company stock.

Microsoft will acquire GitHub subject to closing conditions and completion of regulatory review. The acquisition is expected to close by the end of the calendar year.

GitHub, one of the world’s largest computer code repositories, is home to more than 28 million developers for collaboration and distribution of projects. In recent years, Microsoft has stepped up its activity through several partnerships with GitHub.

The two companies will empower developers to achieve more at every stage of the development lifecycle, accelerate enterprise use of GitHub, and bring Microsoft’s developer tools and services to new audiences, Microsoft CEO Satya Nadella said during a global phone conference.

“GitHub is the destination for developers to learn, share and work together to create software. It’s a destination for Microsoft too. We are the most active organization on GitHub, with more than 2 million commits or updates made to projects,” Nadella said.

GitHub will remain independent, he promised. Once the acquisition closes, Nat Friedman will become GitHub’s CEO and will report to Microsoft Cloud and AI Group Executive Vice President Scott Guthrie. Current GitHub CEO and cofounder Chris Wanstrath will be a technical fellow at Microsoft and also will report to Wanstrath.

“When it comes to our commitment to open source, judge us by the actions we have taken in the recent past, our actions today and in the future,” said Nadella at last week’s conference. “Microsoft is all-in on open source.”

Why GitHub?

Microsoft has been a developer-focused company from its start in creating the platforms and tools it offers today, noted Nadella. The company’s core mission is building technology so that others can build technology.

Microsoft sees three clear opportunities ahead with the GitHub acquisition. First, it will empower developers at every stage of the development lifecycle — from ideation to collaboration to deployment to the cloud, Nadella said.

“Going forward, GitHub will remain an open platform, which any developer can plug into and extend,” he promised. “Developers will continue to be able to use the programming languages, tools and operating systems of their choice for their projects and will still be able to deploy their code on any cloud and any device.”

Second, Microsoft will accelerate enterprise developers’ use of GitHub with direct sales and partner channels, as well as access to Microsoft’s global cloud infrastructure and services.

Third, Microsoft’s developer tools and services will be available to new audiences.

Microsoft recognizes its responsibility with this agreement and is committed to being stewards of the GitHub community, which will “retain its developer-first ethos, operate independently, and remain an open platform,” Nadella said.

Open Source Enthusiasm

While many open source insiders responded to Microsoft’s acquisition of GitHub with high praise, others expressed concerns about unexpected consequences for open source independence.

The acquisition will give Microsoft deeper penetration into the developer mindset, said Nakul Aggarwal, CTO of
BrowserStack.

“I hope this acquisition creates a real win-win situation for all three parties — developers, Github and Microsoft — in this order,” he told LinuxInsider, “but the acquisition will not create that positive impact on the developer community.”

Microsoft as a brand needs to innovate within and solve a genuine developer problem to receive empathy and love from developers, Aggarwal explained. Only then will it reflect that developers really care.

“Currently it looks like a business problem to solve and an acquisition as a way to do it,” he pointed out. “Microsoft gains a deeper Integration with all their developer tools — Visual Studio / Xamarin / Azure, etc. — and more penetration into open source and hence can be known as developer-friendly.”

Business Over Religion

Microsoft’s move to acquire GitHub is a smart business decision, said Jyoti Bansal, CEO of
Big Labs.

It speaks to the massive strategic value of developer platforms and solutions, he told LinuxInsider.

“Satya Nadella has so far done a great job dropping the Windows religion to embrace the reality of the iOS, Android, Linux and the multicloud world, which he will hopefully continue with the GitHub community,” Bansal said.

“By putting [former Xamarin CEO] Nat Friedman in place as a technical CEO, Microsoft is sending a clear message that they’re committed to GitHub and the larger developer ecosystem,” he noted.

The acquisition is a big win for Microsoft, according to Jack E. Gold, principal analyst at J.Gold Associates.

It puts the company ahead in the Web hosting market against fierce competitors Amazon Web Services and Google, he told LinuxInsider.

It creates an incentive for many more app developers to host on Azure, especially in the commercial space where MSFT recently has been less competitive than in the enterprise space.

“That is a win-win for Microsoft, and it doesn’t hurt the developer community either, as they will gain some additional incentives, albeit MSFT-centric, Gold said.

Shifting Focus

GitHub and Microsoft make a perfect fit, as both strive to serve developers of all kinds, said Stefano Maffulli, community director at
Scality.

“I’m surprised that this hasn’t happened before — Microsoft has clearly shifted its focus to developers many years ago,” he told LinuxInsider. “They’ve always claimed to be about developers, and today they put more money where their mouth is. I’m glad the corporation made such a visible U-turn.”

The issue of GitHub’s real commitment to open source also may come into play, he suggested. GitHub has not always been synonymous with open source.

“GitHub has never been open source. Not all code hosted on GitHub is open source at all,” Maffulli said.

Despite its popularity with software developers, GitHub initially did not do enough to educate them about the importance of copyright and licenses for open source, he suggested.

However, both GitHub and Microsoft have greatly improved, Maffulli added.

“They are still proprietary software companies. But at least they now understand, respect and promote open source ideas and practices,” Maffulli said.

Open Source Marketplace

GitHub’s acquisition is good news for open source and perhaps the single most significant validation conceivable that open source *is* the mainstream resource for software development, according to Patrick Carey, director of product strategy at Black Duck by Synopsys.

“Microsoft has always been focused on the needs of the developer, and this acquisition is consistent with that focus,” he told LinuxInsider. “It may seem remarkable that Microsoft, once considered the archenemy of both Linux and open source, would acquire GitHub — perhaps the most prominent piece of open source infrastructure today. But it shows just how much Satya Nadella has changed the game at Microsoft.”

The acquisition makes possible better focus on open source security, Carey added. Microsoft likely will make further strides to embrace open source by providing community developers with new tools to help improve the quality and security of their projects.

Potential for Business Trojan Horse

Microsoft’s acquisition of GitHub makes perfect sense, given the company’s direction under Satya Nadella, said Blair Hanley Frank, principal analyst at
Information Services Group. GitHub is central to the modern developer workflow.

“This acquisition brings Microsoft deeper into that conversation,” he told LinuxInsider. “It shows the company’s embrace of open source and its willingness to evolve to meet the changing needs of its customer base.”

The biggest question is how Microsoft plans to integrate GitHub Enterprise with its other developer offerings, including Visual Studio Team Services. Microsoft does not appear to be integrating the GitHub Marketplace into the Azure Marketplace, Frank said.

Rather, the company sees the GitHub marketplace as a place for it to promote its own software and services to developers. It is important to avoid merging the two at this point, he cautioned, since GitHub’s independence — perceived or otherwise — is key to maintaining goodwill with developers.

“Overall, this is a boost to Azure all-up, since it builds stronger ties between where developers go to build their code and where they can deploy that code in the cloud,” Frank said.

The Edge Factor

Microsoft’s GitHub acquisition is the clearest signal yet of the importance of the cloud-native edge, according to Said Ouissal, CEO of
Zededa.

As cloud developers shift their focus toward taking advantage of Internet of Things data in real time at the “intelligent edge,” they need an on-ramp to the edge — a platform that allows the embedded systems of the world operate like the cloud, he told LinuxInsider.

“Embedded systems today were not even designed for network or optimized for Internet connectivity. They were built for a time when embedded computers were simply ‘set it and forget it’ for years at a time,” Quisssal pointed out.

The developer workflows that Microsoft wants to see drive and influence business processes could spell the end of embedded computing as we know it, he cautioned, if we want to enable those 28 million developers to thrive at the edge.

Suse Linux Enterprise 15 Bridges Traditional, Software-Defined Systems | Enterprise


By Jack M. Germain

Jun 26, 2018 10:53 AM PT

Suse on Monday launched Suse Linux Enterprise 15, its latest flagship operating platform. SLE 15 bridges traditional infrastructure technologies with next-generation software-defined infrastructure, the company said. It will be fully available to existing customers for download or upgrade on July 16.

Suse Linux Enterprise 15 Bridges Traditional, Software-Defined Systems

The company also released enhancements to Suse Manager 3.2, an open source IT infrastructure management solution for Linux, with improvements focused on lowering costs, improving DevOps efficiency, and easily managing large, complex deployments across IoT, cloud and container infrastructures.

Suse Manager helps users meet management challenges created by technology advancements such as software-defined infrastructure, cloud computing and containers, according to the company.

The SLE 15 product family includes seven individual offerings that integrate or supplement a variety of features and functionality. SLE 15 desktop is a standalone product that users can enhance according to their needs as they occur.

SUSE Linux Enterprise 15 - IT Transformation

“The two common elements in SLE 15 are the common code base and modular structure. They can touch every other product,” said Raj Meel, global product and solution marketing manager at Suse.

Evolving Needs

Enterprise users typically have to contend with a mix of IT infrastructures. Architecturally, they have a quagmire to navigate, Meel told LinuxInsider. They may have started out with a monolithic IT structure and then moved into tiered architecture, only to currently find themselves in microservices.

That is where Suse’s multimodal IT concept comes into play. SLE 15 provides a series of bridges for enterprise users to use to bring mixed IT structures into the public cloud without changing what they have.

The SLE 15 operating system addresses the increasing adoption of hybrid, software-defined computing environments spanning physical servers/storage, virtualization, cloud services, containerized workloads, edge computing (IoT) and high-performance computing, noted Charles King, principal analyst at Pund-IT.

“Practically speaking, operating systems like Suse’s flagship Linux are merely one part of increasingly complicated, ever larger enterprise IT infrastructures,” he told LinuxInsider. “As a result, with these new solutions Suse is letting customers know it has their backs wherever their IT resources and workloads reside.”

The new OS includes new function and support features focused on lowering costs, improving management of increasingly complex IT environments, and enhancing DevOps engagements and efficiency — all top-of-mind concerns for Suse customers, especially mid-sized and larger enterprises, King pointed out.

What Suse Released

Suse Linux Enterprise 15 is a modern, modular operating system that helps simplify multimodal IT. SLE 15 makes traditional IT infrastructure more efficient and provides an engaging platform for developers. As a result, customers can easily deploy and transition business-critical workloads across on-premises and public cloud environments, according to Suse.

“Organizations today face increasing pressure to become more agile and economically efficient in order to grow, compete and survive,” said Suse CTO Thomas Di Giacomo. “They must leverage digital assets, information, and an explosion of new infrastructure software innovation to fuel and enable their digital transformation.”

Emerging infrastructure technologies built on open source and Linux create new levels of freedom and flexibility, and Suse Linux Enterprise 15 provides the foundation for this freedom and flexibility, said Di Giacomo. It enables each customer to operate effectively, regardless of their particular IT requirements.

The SLE 15 platform includes the following:

  • SLE for Intel/AMD x86-64, POWER, ARM, z Systems and LinuxONE
  • SLE Server for SAP Applications
  • SLE High Performance Computing
  • SLE High Availability Extension (includes Geo Clustering)
  • SLE Live Patching
  • SLE Desktop
  • SLE Workstation Extension

Suse 15 Primer

The latest OS is designed to help organizations transform their enterprise systems to embrace modern and agile technologies. Multiple infrastructures for different workloads and applications are needed, which often means integrating cloud-based platforms into enterprise systems, merging containerized development with traditional development, or combining legacy applications with microservices, according to Suse.

The platform uses a common code base to ensure application mobility across multimodal IT environments. Whether customers build microservices using Suse’s Containers as a Service (CaaS) Platform, deploy the latest SAP applications on Suse Linux Enterprise Server, or use Suse OpenStack Cloud to manage system resources, the common code base ensures consistency and helps them move application workloads transparently across traditional and software-defined infrastructure.

In addition, through Suse Linux Enterprise bring-your-own-subscription programs, customers easily can transition to or leverage a public cloud, such as Amazon Web Services, Google Cloud Platform or Microsoft Azure.

Operating systems remain a foundational building block for modern infrastructure. Linux has become a preferred platform for the cloud and for modern cloud-native application development, according to IDC. Linux also has gained stature as a preferred development platform for most independent software vendors (ISVs).

Linux is used widely for hosting traditional and next-generation applications across bare-metal, virtual and container-based delivery systems. Suse Linux Enterprise comes out at the top for SAP applications, mainframes, high-performance computing, and other key Linux enterprise-centric use cases, according to IDC.

SLE 15’s Modular Plus architecture addresses new challenges customers face when introducing innovations to make existing traditional IT infrastructures more efficient. Everything in SLE 15 is a module, so Suse can issue updates and patches more frequently. The modular approach lets customers install only the features they need, which simplifies planning and reduces risk.

How Multimodality Works

Traditional infrastructure, software-defined infrastructure, and application-oriented architectures coexist in a multimodal IT environment. Bridges are needed to move workloads from on-premises to the cloud, and to leverage data centers for container applications, said Suse’s Meel. SLE 15 facilitates a mixed IT Infrastructure where servers reside within a traditional infrastructure and applications run on a software-defined infrastructure.

For example, with a traditional infrastructure, enterprises run applications like SAP, SQL and Oracle. With a software-defined infrastructure, users run containers and applications. SLE 15 allows the creation of bridges across mixed IT systems through a process called “application mobility.”

SLE 15 sits in the middle, with container apps to bridge traditional platforms such as virtual machines, and physical servers to integrate with the software-defined infrastructure of the public cloud.

Multimodal IT provides a mix of deployment scenarios spanning traditional and software-defined infrastructures. Storage devices, virtual machines and physical servers navigate to the OpenStack cloud and then use SLE 15 as a bridge to the public cloud.

SUSE Linux Enterprise 15 - Multimodal IT Deployment Scenarios

Application delivery is available via container management (Suse Container as a Service Platform) and Platform as a Service (Suse Cloud Application Platform).

Software-defined infrastructure can be driven by private cloud / IaaS, Suse OpenStack Cloud, compute (container and virtual machine), storage (Suse Enterprise Storage) and networking (SDN and NFV), operating system (Suse Linux Enterprise Server) and physical infrastructure (Server, Switches and Storage).

Bridging the Gap

From the customer perspective, what customers really want is keep their existing structure and maximize it the best that they can, said Meel. Bridging is the key to providing this type of solution.

“The alternative for enterprises is to modernize their IT completely. They may want to connect containers to your data center. Or they move their applications from on-premises to cloud. That is one of the largest use cases we are seeing,” he said.

Those are the bridges that customers are looking for. How can they get there easily? Depending on what they have and where they want to go, they may need one or two or three bridges. Suse even has a bring-your-own-cloud subscription bridge, added Meel.

“We call it a ‘multimodel OS,’ because the OS is not for one specific purpose. Instead, it is solving different use cases for different people. You can start with a minimally viable system and then add what you need. You can build your own platform. You can add modules as you want,” he said.

SUSE Linux Enterprise 15 - Building Bridges with Multimodal OS

Most of Suse’s customers already are at that point. They have a huge IT structure that they manage.

“They do not want to change it too much. That is where the modular architecture really can help them,” said Meel.

Derived Benefits

The latest SLE 15 releases offer a trilogy of benefits to those making the upgrade: Suse’s platform is developer-friendly; it provides the latest in high-performance computing; and it provides key integration with SAP applications.

SLE 15 accelerates an enterprise’s transition from a free developer subscription or community Linux (openSUSE Leap) setup to a production deployment of fully supported enterprise Linux. It is designed for integration into commonly used modern development methodologies like DevOps and CI/CD. It also provides users with a faster time-to-market cycle by leveraging open source technology, methods and expertise.

Businesses have been recognizing that a high-performance computing infrastructure is vital to supporting the advanced analytics and simulated modeling applications of tomorrow.

Suse Linux Enterprise HPC 15 addresses this growing market with a comprehensive set of supported tools specifically designed for the parallel computing environment, including workload and cluster management. HPC 15 supports x86-64 and Arm-based HPC clusters on the full range of hardware used today for HPC — from low-cost to high-end supercomputers.

Suse Linux Enterprise Server 15 for SAP Applications reduces downtime, optimizes performance, and makes deploying and managing SAP systems easier. New capabilities include non-volatile dual in-line memory module (NVDIMM) support for diskless databases, and enhanced high-availability features for IBM Power Systems.

Workload Memory Protection is a new feature that provides an open source-based, more-scalable solution to sustain high performance levels for SAP applications.

“Suse keeps on churning out great open source software that customers want to buy,” said Stefano Maffulli, community director at
Scality

“They may not catch the same spotlight as the other Linux distributions, but they are still there, plowing through release after release with the same German solidity of the early days,” he told LinuxInsider.

Suse is one of the main contributors to lots of open source projects, Maffulli added. “Just look at their
history of contributions to OpenStack, for example — and they package it professionally.”

More Infrastructure Management

Suse Manager 3.2 lowers costs and simplifies deployment while easily scaling larger environments for public cloud and Kubernetes infrastructures. It also helps customers improve DevOps efficiency and meet compliance requirements with a single tool that manages and maintains everything from edge devices to Kubernetes environments.

In addition, Suse Manager makes it easy to manage large, complex deployments with new extended forms-based user interface capabilities.

Additional enhancements in SLE 15 include support for nonstop IT with the integration of geo clustering within high availability extension. This lets users easily connect data centers across the world while providing a resilient and highly available infrastructure.

How to Install and Use Flatpak on Linux | Linux.com


The landscape of applications is quickly changing. Many platforms are migrating to containerized applications… and with good cause. An application wrapped in a bundled container is easier to install, includes all the necessary dependencies, doesn’t directly affect the hosting platform libraries, automatically updates (in some cases), and (in most cases) is more secure than a standard application. Another benefit of these containerized applications is that they are universal (i.e., such an application would install on Ubuntu Linux or Fedora Linux, without having to convert a .deb package to an .rpm).

As of now, there are two main universal package systems: Snap and Flatpak. Both function in similar fashion, but one is found by default on Ubuntu-based systems (Snap) and one on Fedora-based systems (Flatpak). It should come as no surprise that both can be installed on either type of system. So if you want to run Snaps on Fedora, you can. If you want to run Flatpak on Ubuntu, you can.

I will walk you through the process of installing and using Flatpak on Ubuntu 18.04. If your platform of choice is Fedora (or a Fedora derivative), you can skip the installation process.

Installation

The first thing to do is install Flatpak. The process is simple. Open up a terminal window and follow these steps:

  1. Add the necessary repository with the command sudo add-apt-repository ppa:alexlarsson/flatpak.

  2. Update apt with the command sudo apt update.

  3. Install Flatpak with the command sudo apt install flatpak.

  4. Install Flatpak support for GNOME Software with the command sudo apt install gnome-software-plugin-flatpak.

  5. Reboot your system.

Usage

I’ll first show you how to install a Flatpak package from the command line, and then via the GUI. Let’s say you want to install the Spotify desktop client via Flatpak. To do this, you must first instruct Flatpak to retrieve the necessary app. The Spotify Flatpak (along with others) is hosted on Flathub. The first thing we’re going to do is add the Flathub remote repository with the following command:

sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Now you can install any Flatpak app found on Flathub. For example, to install Spotify, the command would be:

sudo flatpak install flathub com.spotify.Client

To find out the exact command for each install, you only have to visit the app’s page on Flathub and the installation command is listed beneath the description.

Running a Flatpak-installed app is a bit different than a standard app (at least from the command line). Head back to the terminal window and issue the command:

flatpak run com.spotify.Client

Of course, after you’ve re-started your machine (upon installing the GNOME Software Support), those apps should appear in your desktop menu, making it unnecessary to start them from the command line.

To uninstall a Flatpak from the command line, you would go back to the terminal and issue the command:

sudo flatpak uninstall NAME

where NAME is the name of the app to remove. In our Spotify case, that would be:

sudo flatpak uninstall com.spotify.Client

Now we want to update our Flatpak apps. To do this, first list all of your installed Flatpak apps by issuing the command:

flatpak list

Now that we have our list of apps (Figure 1), we can update with the command sudo flatpak update NAME (where NAME is the name of our app to update).

So if we want to update GIMP, we’d issue the command:

sudo flatpak update org.gimp.GIMP

If there are any updates to be applied, they’’ll be taken care of. If there are no updates to be applied, nothing will be reported.

Installing from GNOME Software

Let’s make this even easier. Since we installed GNOME Software support for flatpak, we don’t actually have to bother with the command line. Don’t be mistaken, unlike Snap support, you won’t actually find Flatpak apps listed within GNOME Software (even though we’ve installed Software support). Instead, you’ll find support through the web browser.

Let me show you. Point your browser to Flathub.

Let’s say you want to install Slack via Flatpak. Go to the Slack Flathub page and then click on the INSTALL button. Since we installed GNOME Software support, the standard browser dialog window will appear with an included option to open the file via Software Install (Figure 2).

 

This action will then open GNOME Software (or, in the case of Ubuntu, Ubuntu Software), where you can click the Install button (Figure 3) to complete the process.

Once the installation completes, you can then either click the Launch button, or close GNOME Software and launch the application from the desktop menu (in the case of GNOME, the Dash).

After you’ve installed a Flatpak app via GNOME Software, it can also be removed from the same system (so there’s still not need to go through the command line).

What about KDE?

If you prefer using the KDE desktop environment, you’re in luck. If you issue the command sudo apt install plasma-discover-flatpak-backend, it’ll install Flatpak support for the KDE app store, Discover. Once you’ve added Flatpak support, you then need to add a repository. Open Discover and then click on Settings. In the settings window, you’ll now see a Flatpak listing (Figure 4).

Click on the Flatpak drop-down and then click Add Flathub. Click on the Applications tab (in the left navigation) and you can then search for (and install) any applications found on Flathub (Figure 5).

Easy Flatpak management

And that’s the gist of using Flatpak. These universal packages can be used on most Linux distributions and can even be managed via the GUI on some desktop environments. I highly recommend you give Flatpak a try. With the combination of standard installation, Flatpak, and Snaps, you’ll find software management on Linux has become incredibly easy.
