Не может установить что-либо с помощью склонного - добирается

Когда я пробую, например:

sudo apt-get install gparted

Я получаю следующую ошибку:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
gparted is already the newest version (0.25.0-1).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libpcap0.8 : Breaks: libpcap0.8:i386 (!= 1.7.4-2) but 1.4.0-2 is to be installed
 libpcap0.8:i386 : Breaks: libpcap0.8 (!= 1.4.0-2) but 1.7.4-2 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

(Да, я знаю, что GParted уже установлен. Это - просто пример). Ubuntu пытается помочь мне и предлагает использовать sudo apt-get -f install. Но когда я пробую его:
