When I try to upgrade (a copy of) my main system from Lucid to Precise with the command "do-release-upgrade -d", I get the following message:
| 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. Well, I do have packages installed which were not provided by Ubuntu and I tried to upgrade to a pre-release version. Does it really mean I should not report the problem? After all I found a workaround for this situation by removing some packages which were installed from the Ubuntu repos. Here is a summary of the workaround: 1. I had installed the package "gcj-jdk" including dependencies. Removing these packages let the upgrade continue without the error message above. 2. However the upgrade stopped after a few packages were installed with a failure message concerning the package "lib32asound2". After also removing the packages which depended on this package (ia32libs, wine1.2, etc.) from a fresh copy of the system, I could successfully run the upgrade. 3. After the first reboot, I got the error message "Could not start D- Bus. Can you call qdbus?" like it is mentioned at [1] (this is a Kubuntu system btw). After manually installing the package "qdbus", the system worked. Please advise if and what I should report at launchpad.
