Я полностью в тупике. Проблема заключается в следующем.

Я не знаю, что удалить / удалить. Какие-либо предложения? Заранее спасибо.

EDIT # 1

Добавление вывода от предложения Чарльза Грина, потому что это невозможно прочитать в комментарии.

user@mycomputer:~$ sudo apt-get remove --purge openjdk-7-source

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 openjdk-7-jdk : Depends: openjdk-7-jre (= 7u55-2.4.7-1ubuntu1) but 7u71-2.5.3-0ubuntu0.14.04.1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Второе предложение Чарльза Смита.

Однако, если я попытаюсь sudo apt-get -f install, Я все еще получаю сообщение об ошибке.
