Public bug reported: I am unable to determine which package needs to be removed. I am seeing the error below:
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. I turned off all "Other Software" sites listed under "Software Sources". I ran the following with no change: root@allen-laptop:~# apt-get autoclean Reading package lists...
