What are the main differences between Ubuntu, Fedora, and Debian?

Actually, you might not even need to switch from Mint! Since Mint is based on Ubuntu, that Autofirma app should work just fine on it. If it's compatible with Debian, it should run on Mint without any issues. Why not try it out before making a switch?

Definitely try out (K)Ubuntu since it has KDE by default—it's user-friendly and built on the same structure as Mint. On top of that, Debian offers stability and updates every couple of years, but for everyday use, I'd suggest going with (K)Ubuntu or Fedora for a more responsive experience.

When it comes to the differences, Ubuntu is based on Debian and aims for newer packages but uses Snap packages, which can be annoying. Fedora, on the other hand, uses DNF, is cutting-edge, and updates every six months. If stability is what you're after, Debian is great, but if you want something a bit more modern or user-friendly, Ubuntu or Fedora might be better for KDE. If you're worried about resource usage, both Debian and Mint are pretty light!

If you don't want to switch, just grab the Debian/Ubuntu zip for Autofirma. Inside, you’ll find a `.deb` file you can install using the terminal with `sudo apt install .deb`. Super easy! Also, if you uncompress the downloaded file, there's a link to download Autofirma for Linux, which will work on Mint too.
