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?
