  • Would it be enough to be able to run .deb packages on fedora?

    Unpacking a .deb on Fedora, or unpacking an .rpm on Ubuntu isn’t a big deal. The files inside are often actually identical.

    But would not be useful because the files inside usually rely on shared libraries, which may or may not already be installed. Those shared libraries are installed in different places on each Linux distro. Figuring out which ones to ask for (and making sure the program can find them) is the real work that the .Deb or .RPM installers do.

    A fun way to try this out is with Portable Apps. Anything called a “portable app” either doesn’t use additional libraries, or carries the libraries it needs with it.

    If you find a portable app for Ubunutu, there’s a good chance the Fedora version is an identical file, and works fine on Ubuntu. There’s lots of reasons it might not work, but it can be fun to try.

    For the most part, the only reason any Linux program is unavailable on a different version of Linux is that no one has bothered to build the necessary installer for that combination of program and OS.

    .RPM was supposed to solve this by being universal, since any other OS can implement it to match .Deb was supposed to solve this by being universal, since any other OS can implement it to match (about 60% actually do). I think Flatpacks and Snaps might solve this by being universal, at some point…
