[Bug 873858] [NEW] can't upgrade from 11.04 to 11.10

[John]

Public bug reported:

When trying to upgrade from 11.04 to 11.10, this is what I get:

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.
