Как исправить неисправные зависимости после прерванной установки gnome / libreoffice?

Я использую Ubuntu 14.04 LTS (64 бита) с удаленным Libreoffice и установленным Openoffice 4.1.0.

Моя система пакетов не работает, и я не могу ничего установить или удалить, пока не устраню проблему. Я искал ask-ubuntu и прочитал множество «решений» для сломанных зависимостей, но ни одно из них не помогло мне в затруднительном положении.

Вот что я сделал, чтобы попасть в нынешний тупик.

Я пытался установить рабочий стол gnome с помощью «Центра программного обеспечения», но я не осознавал, что установка рабочего стола также пыталась установить Libreoffice. В процессе установки процесс выплюнул ошибку и остановился. Использование «sudo apt-get install -f» приводит к выводу ниже.

Я хотел бы исправить зависимости, чтобы избавиться от сломанной установки Libreoffice, но я не знаю, с чего начать.

sudo apt-get install -f
