I’ve been using linux for some time now, i would still say i’m quite a noob but i’ve tried different desktop environments, for my experience i found GNOME to always be suited for me, anyway i heard many good opinions on KDE and i would love to try that too, i’ve tried cinnamon before and couldn’t really see myself using it, i’ve seen Kubuntu and looks quite lovely, what’s in your opinion the distro that best implements KDE on Debian or preferably Ubuntu?
Well, why not Debian itself. However if you want something Debian based with ease of use then check Spiral linux
Opensuse tumbleweed is woth checking as well. It has a good KDE implementation and you may like Yast and Zypper.
I installed debian with KDE, so far looks great, not too many problems in setting up my environment, KDE is great and i love the stability that debian seem to be based on, i don’t really care if my software gets a couple of year old, as long as it keeps working without problems!
Flatpak can get you the latest version, not everything can installed using flatpak though.
