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?
I forgot about PPAs - I don't normally use Ubuntu-derivatives. PPAs are a little more dangerous if I recall correctly right? Firstly it should be an official PPA from the software developer, and secondly because it's a repo you have to make sure that it isn't going to eventually pull in packages that replace/break your system.
Safety for the ones I've listed:
Flatpaks - Containerized, separate from system packages
Cargo - Manual compilation, /home installation
deb-get - One-off .deb from official source and doesn't try to pull any other dependencies in - worst case you fail the dependency check I think?
Homebrew - Pre-compiled binaries or manual compilation if you choose, /home installation with local dependency network
Nix Package Manager - Roughly the same as Homebrew, /home installation
bin - Probably a single statically-linked executable, /home installation
Docker - Containerized, separate from system
Compile and install it yourself - Highest potential for things to go wrong as you're messing with system packages and probably working off of some developer's questionable compilation instructions (or even lack thereof).
Worst thing about PPAs is their maintainers don’t keep up with the base Ubuntu version and then you have to disable the PPA on the next version upgrade, or you end up seeing someone with repositories for Ubuntu 16.04 on 22.04 and wondering why apt is returning errors. Containers are a much better modern solution.
