Can't calculate the upgrade because of blcr-dkms_0.8.2-13

[Matus]

Binary package hint: update-manager

Update manager shows window with text:

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
