Plasma6 has just dropped and updating astroarch could lead to some issues. Luckily enough I got some very early reports and did my best to try to patch them.
If you update now with update-astroarch it should fix all the issues, if not please bear with us. Plasma6 is a MASSIVE update but we will work hard to solve all of your problems!
Plasma6 seems to be even slightly faster and less resource hungry than plasma 5 and I think the look and the feeling is pretty great!
