Schlechte Beurteilung für Ubuntu 22.04 LTS von DistroWatch
DistroWatch: Ubuntu 22.04 LTS
”I think the launch of Ubuntu 22.04 is a clear sign Canonical is much more interested in publishing releases on a set schedule than producing something worthwhile. This version was not ready for release and it is probably going to be a costly endeavour to maintain this collection of mixed versioned software and mixed display server and mixed designs for a full five years. It's a platform I would recommend avoiding.”
”What I’d really like to see more of are more non-technical contributors. I mean, yes, we can always benefit from more packagers and coders and engineers, but I think what we really need desperately are writers, designers, artists, videographers, communicators, organizers and planners.”
