I'm updating from 10.04 to 10.10 using the update manager. During the update I get the following error message:
Could not determine the upgrade
An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generate 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 of Ubuntu
* Unofficial software packages not provided by Ubuntu
If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report.
Ok so I am not upgrading to or running a pre-release version of Ubuntu but I do now know whether an unofficial software package is causing the issue. I'll include the main.log file to give you more information about the error. What do I do?
