Ошибка установки или обновления из-за dpkg и linux-image-extra-3.11.0-15-generic

Я пытался найти и найти много статей, постов и обсуждений, связанных с этой ошибкой, но мне еще предстоит найти что-нибудь, что скажет мне, как ее исправить.

Я запустил следующее:

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

Я в растерянности и не знаю, куда идти.
