Ошибка при установке mysql-server-5.5

Я пытаюсь запустить

sudo apt-get upgrade

Но он дает мне ниже результата. Я попытался запустить

sudo apt-get -f install

, но нет никакой разницы.

Также я попытался запустить dpkg --configure -a, но он тоже беспомощный. Выход:

dpkg: dependency problems prevent configuration of mysql-server-5.5:
