ПостThis is the problem:

This is the problem: Dependency Hell -You have shared libraries -Developers build software using different versions of those shared libraries -The developers of those shared libraries don't give a shit about breaking stuff when updating them as well -How in the world you coordinate any shit in your system without breaking it? So the solution is: Package managers of the distribution hold some set of versions of the same libraries, which are compatible with each other and the software packed in the distribution The problem? Developers of apps might use old or newer versions of those libraries depending on the distro, so now developers of software have to build binaries for every damn distro, including distro versions, or force you to upgrade or downgrade packages, breaking other apps The solution? Flatpak which functions as a "virtual distro", providing runtimes, packed with a set of libraries and people developing software for flatpak, have to adjust to one of the runtimes Software can run on different versions of different libraries, they are self-contained, they use each one a version of the runtime And developers should either build for flatpak, or statically link shit, they shouldn't force you to update packages or downgrade packages so the apps they build work for you, since that actually breaks other shit
