So I'm trying to upgrade from Onereic to Pangolin using the Update Manager. Fine. Except that I get this error in the "Setting new software channels"
phase;
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 do have a lot of PPAs, but I've disabled all of them. Someone told me to use ppa-purge on all of them, but I don't think I'm doing it correctly. Remember, I've successfully upgraded to 11.10 FROM 11.04 with all of these PPAs activated. Any tips?
