After unsuccessful upgrade of Gnome3 packages in new Precise Pangolin 64-bit environment I get this error at installing
The following packages have unmet dependencies: gnome-shell-extensions : Conflicts: gnome-shell-extensions-user-theme but 3.2.0-2~webupd8~oneiric is to be installed E: Unable to correct problems, you have held broken packages.
I tried to remove by running
sudo apt-get purge gnome-shell-extensions-user-theme but get this:
Package gnome-shell-extensions-user-theme is not installed, so not removed
My Gnome Classic profile works well but Gnome3 session can't run.
How to resolve this error?
