@variablepulserate yeah, AppImage, Snap, and Flatpak were different angles to solve the same problem, but it just resulted in three different ways to get software aside from apt, yum, and pacman … depending on which distro you’re using. Then there’s the isolation issues with some of those installation methods … or hardware visibility issues … or discoverability …
Oh, and if you’re working with Python apps, then you don’t use any of those. You need to use pip … unless the app is written in Python 3, then you install with pip3.
These tools are fine for people who have invested decades with Linux already, but it’s a massive hurdle for newer people who just want something that isn’t Windows … 😕
