не мог выполнить dist-обновление

я пытаюсь выполнить следующее, но получаю ошибки. Как я разрешаю его?

nas@nas:/boot$ sudo apt-get dist-upgrade

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 linux-generic : Depends: linux-headers-generic (= 3.2.0.107.123) but 3.2.0.120.135 is installed
 linux-image-generic : Depends: linux-image-3.2.0-107-generic but it is not installed
E: Unmet dependencies. Try using -f.
nas@nas:/boot$

Я попытался работать склонный - получают установку-f, но все еще получают ошибки

nas@nas:/boot$ sudo apt-get -f install
