when i enter the system setting from destop (change desktop background), i found "Appearance" lost, i had done the "sudo apt-get install ubuntu-system-settings".

Thank you for your bug report. There was a transition period where things were buggy, but that should be resolved, is that still an issue?

I could have the same issue.
Symptoms :
 - I cannot change any settings.
 - Appearance settings are greyed out or reset instantly when I click to change any parameter.
 - cannot change background
 - cannot change launcher icons

At each session startup, I can see my usual background and unity launched replaced by default ones !

unity-control-center logs this when I try to change background :

(unity-control-center:9702): dconf-WARNING **: failed to commit changes to dconf: GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._g_2dfile_2derror_2dquark.Code2: Cannot open dconf database: Failed to open file '/home/user/.config/dconf/user': Permission denied

The problem was the following : /home/user/.config/dconf/user file owner changed to root:root during upgrade.
