Plasma 6 landed in opensuse. However, I recommend to do it in tty because if you do it in plasma the upgrade will be incomplete because the shell will crash in the middle of update without installing all. In case this happen to anyone, just reinstall plasma 6 pattern and it will go without problems
Been using Plasma 6 in Arch for a bit now and I have to say I’m very impressed. The 6 branch has fixed a variety of annoying little quirks that bothered me about KDE. It feels very good to use.
