[Bug 1001283] [NEW] unity package marked for removal but is blacklisted, stoppin me from upgrading to 12.04

[Ben Derwent-Smith]

Public bug reported:

i am trying to update to 12.04 and getting the error:
An unresolvable problem occurred while calculating the upgrade:
The package 'unity' 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.

WHAT DO I DO????
