Невозможно создать файл (во время обработки): файловая система только для чтения

Я пытаюсь обновить программное обеспечение, но получаю следующую ошибку:

The package system is broken
Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f
The following packages have unmet dependencies:
linux-image-generic-lts-quantal: Depends: linux-image-3.5.0-45-generic but it is not installed***

После этого я попытался установить пакет linux-image-3.5.0-45-generic из центра программного обеспечения, но у меня есть то же диалоговое окно, что и выше заявив, что у меня есть неудовлетворенные зависимости, и мне нужно установить тот же пакет, чтобы установить себя.

$ sudo apt-get install -f

И вывод uname -r показывает,

$ uname -r

Я набрал команду sudo mount в терминале, а следующий вывод
