Compile from source.

it's called snap cos thats what the community will do to your bones if you use it. apparently

OCI

I don’t really like neither of the 3, personally. But I understand the need and the benefits

For some reason the first time I read it, I thought it was an "L" so now I always call them "Apple mages"

How do you guys get software that is not in your distribution’s repositories?

Since i use a gaming arch based distro (Cachyos) the aur

.deb first and then flatpak if not available as on deb repo or if deb version is outdated. Never used appimage or snap. Rpm just as good as deb when I use Fedora. Flatpaks are much larger in size which is why I first go with the deb version.

Nix, if not in nix pkg for nix, then nix

Install from source if there isn't a repo for the software.

I understand appimages. I use them exclusively. Can someone explain what flatpak and SNAP are and how they work? I have autism so please be as clear and concise as possible?

I have yet to find a need to go outside of the Debian repos.

AppImage, build from source, or don't bother
