Установка / удаление не работает

при выполнении sudo apt-get install или аналогичных команд, я получаю это сообщение:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 postgresql-client-9.1 : Breaks: postgresql-9.1 (< 9.1.11-1.pgdg12.4+1) but 9.1.10-1.pgdg12.4+1 is to be installed
 postgresql-contrib-9.1 : Depends: postgresql-9.1 (= 9.1.11-1.pgdg12.4+1) but 9.1.10-1.pgdg12.4+1 is to be installed
 synaptic : Depends: libvte9 (>= 1:0.24.0) but it is not going to be installed
            Recommends: rarian-compat but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Ubuntu Software Center и Update Manager тоже не работают - Software Center продолжает пытаться восстановить, но это никогда не бывает успешным, установка apt-get -f не помогает (восстановление отменяется из-за этих пакетов). Все сообщения об ошибках имеют отношение к этим пакетам.

Есть ли что-то, что я могу сделать, чтобы это заработало?
