Как восстановить dpkg из поврежденных загрузок?

Я только что обновился до 10.10 RC ранее и у меня было несколько проблем с графическими драйверами (x не запускался) Но я исправил это сейчас. Когда я запускаю 'sudo apt-get install -f', я получаю это:

will@UbuntuBox:/mnt/slax$ sudo apt-get install -f
