So I did a fresh installation of 14.04 lts today and i wanted to install gnome shell or ubuntu-gnome-desktop on my linux but it is a problem there :
Aspire-E5-571G:~$ sudo apt-get install gnome-shell

So.. my question is what is going on here. Btw i used to get gnome-shell not even once and it was working. Anyway i tried everything from another topics and from here : How do I resolve unmet dependencies after adding a PPA? as well. Nothing worked.
