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?
Your only option is universal formats like Flatpak and AppImage. I would recommend against random deb packages or compiling from source unless it’s some very tiny obscure utility that will not need any updates in the foreseeable future (so something like j4-dmenu-desktop or a fetch script).
