Running the latest Precise development build minus the ten updates I cannot get because of this error. I am not able to upgrade anything on my Precise Desktop, but I can check for updates. Additional information update-manager told me to upload:
'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'
Will upload a screenshot as proof.
