You should get a better package manager/distro. With emerge or pacman, it's easy to find/write your own ebuild/pkgbuild, way better than adding ppas.

Fair. I'll soon give asahi a try on a refurb mac, so then I'll be try arch style package management.

Not sure if adding ppas is the problem, i think that's ok, but making packages when none exist is more of a hassle.
