Не мог зафиксировать поврежденную систему пакета

После того, как мне (мучительно) удалось установить Skype на моем LTS Ubuntu 12.04, я испытываю, с тех пор несколько месяцев назад проблема пакетов я не могу зафиксировать.

Взгляните к моему последнему сообщению для знания то, что вызвало эту проблему: Skype Установки на Ubuntu 12.04 64-разрядный LTS

Если я пытаюсь установить системные Обновления завершения Менеджера обновлений неожиданно заявление, что система пакета повреждается и бросает следующую ошибку:

The following packages have unmet dependencies:

grub-efi-amd64: Depends: grub2-common (= 1.99-21ubuntu3.9) but 1.99-21ubuntu3.10 is installed
                Depends: grub-efi-amd64-bin (= 1.99-21ubuntu3.9) but 1.99-21ubuntu3.10 is installed

Если я работаю sudo apt-get -f install для устранения потенциальных проблем пакетов, я получаю следующее:

Мое понимание - то, что первопричина не встречена dependecies пакетов grub-efi-amd64 и grub-efi-amd64-signed, таким образом, я попробовал то, что описано здесь, Как я разрешаю невстреченные зависимости после добавления PPA? но проблема все еще сохраняется.

Я не уверен, устранило ли удаление конфликтующих пакетов проблему, но я еще не сделал этого, поскольку я боюсь, что мог разрушить свою систему, поскольку это имеет начальную загрузку EFI, и я загружаю его с GRUB. По той же причине я не попытался работать sudo apt-get -u dist-upgrade, поскольку, возможно, конфликтующие пакеты могли быть автоматически удалены.

Я хотел бы знать, был ли у других подобный опыт, а также возможные решения этого.
