blcr-dkms: Unresolvable problem while calculating upgrade from Lucid to Maverick

[jbatista]

Binary package hint: update-manager

Update manager fails to upgrade from Lucid (10.04) to Maverick (10.10) with the following message (some parts in native language):

----8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<------
"An unresolvable problem occurred while calculating the upgrade:
Tentando instalar a versão 'blcr-dkms_0.8.2-13' da lista negra

 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

Se nenhum destes se aplicar, reporte esse bug sobre o pacote 'update-manager' e inclua os arquivos em /var/log/dist-upgrade/ nessa notificação de bug."
----8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<------

When attempting to run from console, the following output is produced:

----8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<------
