Public bug reported: the following exception was generated once I selected the "Upgrade to 11.1" button via the "Update Manager":
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 have already executed 'ubuntu-bug update-manager' command.
