It’s not just the AUR, but that’s part of it. Every time I use Debian, I’m shocked by how difficult it is to install any proprietary software. I tried to make it easy on myself by installing Flatpak, but even that didn’t seem to work on my system for some reason. I’m sure it was a fixable problem, but I just found myself fighting it more than I liked. The Arch wiki is also incredible and has been a great help when I’ve encountered similar issues over there.
