Public bug reported: I run update-manager -d to upgrade from Ubuntu 10.04.4 LTS (as per lsb_release) t0 12.04 LTS
During 'Setting new software channels' (calculating the changes) I'm told : ------ Could not determine 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. ------ I've removed every 3rd party repository from my sources (via software sources). I don't believe I'm running a pre-release version and I certainly don't want to upgrade to one.
