Comment 20 for bug 555729

I can't upgrade my workstation from lucid to maverick due to this bug, so I'm reopening the update-manager task.

None of the following packages is installed in the workstation, so I don't know why u-m is trying to install it.

All I get is the following messagem in a window and then it aborts:

----
An unresolvable problem occurred while calculating the upgrade:
Trying to install blacklisted version 'blcr-dkms_0.8.2-13'

 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 against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report.
