Tente visualizar os últimos pacotes instalados [aqui] e determine se esses são os causadores de erros, também não instale pacotes de fora do synaptic [exceto se você cuidadosamente registra estes pacotes]
Se você não sabe como resolver o problema, poste os últimos pacotes instalados, [todo o histórico não é necessário, apenas os últimos 3 ou 4 pacotes]
