Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade:
The package 'update-manager-kde' 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

This is most likely a transient problem, please try again later.

What version are you trying to update? Are you trying to do a release update within the Update Manager (for instance updating from 9.10 to 10.04)? If you are trying that it simply won't work.

Alpha problems with update-manager.I used the terminal for the updates and it worked.
