Hello, i am currently looking for a Linux distribution with these criteria:
-it should be more or less stable, comparable to Ubuntu with or without LTS //
-it should not be related to IBM to any way (so no fedora/redhat) //
-it should not feature snaps (no Ubuntu or KDE neon) //
-KDE plasma should be installable manually (best case even installed by default) //
-no DIY Distros //
I've been thinking about using an immutable distro, but if anyone can recommend something to me, I'd be very grateful //
Edit: I'm sorry for the bad formatting, for some reason it doesn't register spaces
people will read stable and instantly comment debian
Jokes aside, given that you said in a comment that it's for non-tech-savvy people, I'd say Linux Mint, partially just because it will look familiar if they've seen any Windows PC.
They have only Cinnamon, XFCE and Mate but for sure you can use whatever KDE Ubuntu LTS has in their repos. In general not a good idea though I suppose.
