• Sorry to ask, I’m not really familiar with Linux desktop nowadays: I’ve seen Flatpak and Flathub talked about a lot lately and it seems to be kinda a controversial topic. Anyone wanna fill me in what’s all the noice about? It’s some kind of cross-distro “app store” thingy?

    • Flatpak is a universal application packaging standard for Linux. It allows devs to create a single application that gets bundled with all necessary dependencies including versioning.

      These apps run in their own semi-isolated “container” which makes immutable distros possible. (Distros like Fedora Silverblue that are effectively impossible to break by installing or removing critical system files.)

      This means that a Linux app doesn’t have to have a .deb version, an .rpm version, or be pre-compiled for any other distros. A user can simply go to Flathub, (the main repository for Flatpak apps), download the flatpak, and install it on their distro of choice.

      It’s quickly becoming the most popular way for users to install apps on Linux because it’s so easy and quick. But there are a few downsides like size on disk, first party verification, per-distro optimizations, and the centralization of application sources. That’s why some users aren’t fully endorsing or embracing how popular they are becoming.

        Cool, thanks for the explanation.

        a single application that gets bundled with all necessary dependencies including versioning

        Does that mean that if I were to install Application A and Application B that both have dependency to package C version 1.2.3 I then would have package C (and all of its possible sub dependencies) twice on my disk? I don’t know how much external dependencies applications on Linux usually have but doesn’t that have the potential to waste huge amounts of disk space?

        • Essentially yes, if you start using lots if older applications or mixing applications that use many different dependency versions, you will start to use lots of extra disk space because the different apps have to use their own separate dependency trees and so forth.

          This doesn’t mean it will be like 2x-3x the size as traditional packages, but from what I’ve seen, it could definitely be 10-20% larger on disk. Not a huge deal for most people, but if you have limited disk space for one reason or another, it could be a problem.

      Most of the issue is that they’re unreliable. Sometimes the app will work. Sometimes it doesn’t. Sometimes you have to fiddle blindly with flatseal settings, which ones? Who knows? Guessing is part of the fun.

      It’d be a great thing if it just worked.

    • Flatpak is the best - thats all you need to know!!!

      But seriously, apart from obvious things other people have said, I would like to add that the HUGE advantage of flatpak is that each app is using its own dependencies, this way you can avoid dependency hell, which is mostly time-consuming and hard to fix.

      yes it’s cross distro, it’s controversial becaune some people don’t want to install apps with their own libraries or dependecies, and some apps are not oficial so they break with the flatpak sandbox

    • I don’t hate flatpaks, but flatpaks require more disk space than the same apps from traditional repositories, and they only support a handful of the most common default themes. Since I only ever use older and slower computers, my disk space is limited, and I like to rice my desktop, I personally avoid them. But your use-case may differ.
