The problem is that I can't remove the gnome-shell and gnome-shell-extensions. When I try to delete with Ubuntu Software Center there is an error:
Package dependencies cannot be resolved
This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.
The following packages have unmet dependencies: gnome-shell-extensions-user-theme: And when I try to delete with terminal: araqkh@araqkh-U30Jc:~$ sudo apt-get purge gnome-shell-extensions [sudo] password for araqkh: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: gnome-shell-extensions-user-theme : Depends: gnome-shell-extensions-common but it is not going to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. araqkh@araqkh-U30Jc:~$

How can I solve this problem?
