"Can't install 'ubuntu-desktop'"

[psyboy55]

Everytime i try to do the distribution update it tells me "Not all updates can be installed." It gives me an option to do a partial upgrade or to close the window. when i click partial upgrade it says "Can't install 'ubuntu-desktop'" "It was impossible to install a required package. Please report this as a bug." What do i do? is this were i'm suppose to report it?

Which version of Ubuntu are you using, and which are you trying to upgrade to? Do you have all repositories enabled?

Go to System > Administration > Software Sources

You need the Main repositories enabled to install ubuntu-desktop
