I upgraded to Ubuntu 11.10, then found that when I try to download the Gnome Desktop Environment from the Software Centre, I get the following message:
Package dependencies cannot be resolved. The following packages have unmet dependencies: gnome Depends: gnome-core(=1:30+1ubuntu1) but 1:30+1ubuntu1 is to be installed.
I'm not offered the Gnome option when I right-click on the password screen.
I've tried the following commands, all gathered from the Web: sudo apt-get install gnome-session-fallback restart; sudo apt-get install gnome-themes-standard; sudo apt-get install gnome panel. None has had the result of allowing me to get and use the Gnome Desktop. I'm a user, not a developer, and I only upgraded to 11.10 because I thought I would have that option.
What can I do?
