Não foi possível calcular a atualização

An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be
caused by held packages.

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 deste se aplica, então por favor relate este erro sobre o
pacote 'update-manager' e inclua os arquivos em
/var/log/dist-upgrade/ no relatório de erro.
