I have started using linux for 6 months since I leave Windows and already tried ubuntu, arch and liked mint besides arch AUR be so useful, but because I have had some issues with rolling release I choose mint, and I sometimes need latest package, there is somehow to install without being though appimage and tarball?
You are missing PPAs from the list even though it needs some attention on which PPA is being used. I used to use the when I was on Mint.
