Flatpak: Software used to deploy software on the Linux platform.

All of these technologies are essentially building an entire OS on top of another OS just to avoid the challenges of backwards compatibility. In doing so, they create far more problems than they solve. Problems of compatibility are best solved by the OS, the real one, not some containerized bastardization on top. We need to make apps that run natively, that use the system libraries as much as possible. We need to drastically simplify everything if we have any hope of attracting proprietary software to Linux. This isn’t an issue specific to video games by the way.

Remember, an AppImage is an application you simply download and run. Anyone can build an AppImage, proclaim it a must-have piece of software, roll something nefarious into it, and make it available for download. Chromebooks are even smaller as they push everything onto cloud storage. Smartphones are starting to run full-fledged Linux distributions.

Flatpak applications are distributed from repositories called remotes. Additionally, third-party remotes are available as well. Red Hat does not support applications from third-party remotes. The libraries that are not available in a runtime are bundled along with the application by the developers. The libraries can also be the different versions of libraries from the ones that are in a runtime and/or patched versions of libraries. You can use the absolute path to the application’s flatpakref to install the application or through Flathub.
