I recently got Ubuntu 12.04 LTS , I had a problem with the shell theme so I looked around
this site and put in the following command:
sudo add-apt-repository ppa:ricotz/testing sudo apt-get install ppa-purge sudo apt-get update sudo apt-get install gnome-shell-extensions sudo apt-get install gnome-shell-extensions-common sudo ppa-purge ppa:ricotz/testing (type N and press enter at the end of the process)
The upgrade manager asked to do a partial update, which I allowed, and then to restart , which I did, now I can't mount to my log on screen. Is there anything I can do besides reinstall?
