Very odd- run
You mention you want to use Gnome shell- to install that runCode:sudo apt-get purge libunity6
Code:sudo apt-get install gnome-shell
A rerun of you command gave me this:
I don't know for sure if:Code:Reading package lists... Done Building dependency tree Reading state information... Done Virtual packages like 'libunity6' can't be removed 0 upgraded, 0 newly installed, 0 to remove and 49 not upgraded.
was said the first time I ran the command.Code:Virtual packages like 'libunity6' can't be removed
