Моя система разбита. Я предполагаю, что-то; проблемы с libqt4-test

Итак, вот в чем проблема: каждый раз, когда я пытаюсь установить пакет, я получаю сообщение об ошибке:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libqt4-test : Breaks: libqt4-test:i386 (!= 4:4.8.1-0ubuntu4.3) but 4:4.8.1-0ubuntu4.2 is to be installed
 libqt4-test:i386 : Depends: libqtcore4:i386 (= 4:4.8.1-0ubuntu4.2) but 4:4.8.1-0ubuntu4.3 is to be installed
                    Breaks: libqt4-test (!= 4:4.8.1-0ubuntu4.2) but 4:4.8.1-0ubuntu4.3 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Затем, когда я вызываю sudo apt-get -f install, я получаю эту ошибку:

$ sudo apt-get -f install

Есть ли у кого-нибудь идеи относительно того, как я могу найти выход из этой дилеммы?
