Ошибка при установке пакетов или обновлении из-за dpkg: ошибка обработки linux-image-extra-3.11.0-15-generic

Несколько дней назад я попытался установить игру через 0ad через терминал. Я случайно закрыл терминал до того, как он был закончен, и теперь я не могу установить или обновить любую программу на моем компьютере. Я бегу 13.10.

Я пытался найти и найти много статей, постов и обсуждений, связанных с этой ошибкой, но мне еще не удалось найти метод, который бы исправил ее.

Я попытался запустить

sudo apt-get clean && sudo apt-get autoremove

, который выводит
