Public bug reported: I got the following error
Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug using the command 'ubuntu-bug update-manager' in a terminal. Pls let me know what further info I should provide. I think the main 3rd party software is Gnome3, but on my two other ubuntu boxes he upgrade went with no problem, though I have gnome3 there too.
