Public bug reported: I have got this pop-up error message while updating from Ubuntu version 11.04 to 11.10:
Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: The package 'postgresql-plperl-8.4' is marked for removal but it is in the removal blacklist. 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.
