Как исправить & ldquo; *: i386 не может быть настроен, потому что *: amd64 в другой версии & rdquo ;?

Мне удалось сломать apt-get, я думаю, что это как-то связано с конкурирующими версиями libqt между суперколлайдером и Skype. Когда я запускаю apt-get -f install, я получаю:

Я читал, что могу это исправить, установив aptitude, удалив и переустановив неработающие пакеты, но не могу установить его с помощью dpkg.
