On a recent clean Kubuntu 11.10 64 bit install, Muon Package Manager and Muon Software Update Center would not work. I would just get a bug report.
I had to do all the updates through Konsole. The only way I could get Muon to work was install an experimental version of Muon through a PPA,
I am not having problems with the experimental version, it seems to work great.
I am not a fan of experimental software and I know the cons of having an experimental PPA, like breaking the program on an update, but should I keep the experimental PPA or disable it and count on stable updates?
If I disable the experimental PPA will that cause problems of reverting to the release I am having problems with?
