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
There are only 3 options I can immediately think of, for you:
Debian
OpenSUSE (Leap)
Slackware
They are ordered from most to least likely to recommend for your criteria i.e I recommend Debian, alternatively Leap, and if you don't like either you can try Slackware, but Slackware is closer to a DIY distro.
As a long term slackware aficionado, I agree that it meets the criteria. But it also is significantly different from other distros in enough ways that you may find yourself relearning things you took for granted. And that is off-putting for a lot of users.
I wanted to like Slackware, I really did, but you're right. It is significantly different and not necessarily in a good way (I'm not bashing Slackware, I'm just saying that Slackware is quite archaic in the way it does things, and that's not always the best way of doing things).
Opensuse Slowroll is a way better approach than Leap. Same for Debian, I would use Kubuntu and desnap it or something, as updates every 2 years is simply outdated quickly.
