How do I install and use the latest version of GNOME 3?
When I try to install Gnome Shell by pressing:
the Software Center opens and says:
There isn't a software package called "gnome-shell,gnome-themes-standard" in your current software sources.
I tried to switch between "Main Server", "Server for United States" and "Server for Lithuania" (my country) it didn't work.
I also checked "main", "universe", "restricted" and "multiverse" didn't work either.
BTW I'm using an upgraded version from Ubuntu 11.04 not a fresh install.
