Пол-установленное ядро, не может установить / удалить что-либо

Ну, у меня есть эта проблема, я не уверен, как я ее получил, но мне нужна помощь.

Прежде всего, мой компьютер запускает версию Ubuntu 14.04.3 LTS, а текущее ядро (тот, который я получаю от uname -r) составляет 3.13.0-63-generic. Скажите, пожалуйста, если вам нужно знать что-нибудь еще.

Моя проблема в следующем: каждый раз, когда я пытаюсь установить / удалить какой-либо пакет, либо с помощью apt-get, либо с помощью Synaptic, я получаю сообщение об ошибке об этих пакетах :

Вывод (например, когда я запускаю sudo apt-get install 'package-name'), я получаю:

Если есть какая-то другая информация, которая вам нужна, я рад дать вам.

Если кто-нибудь может мне помочь, это будет означать все мне. Мне действительно нужно иметь возможность устанавливать / удалять пакеты на моей машине, поэтому мне нужно как можно скорее решить эту проблему.

PS: помните, что я не эксперт Ubuntu / Linux. [ ! d15]
