Попытка работать автоудаляет с Кв. - добираются, но проблемы ядра получения

Когда я пытаюсь сделать sudo apt-get autoremove или sudo apt-get dist-upgrade (и другие также, но я думаю, что они являются представительными на данный момент), я продолжаю получать ту же ошибку:

Errors were encountered while processing:
 linux-image-extra-3.13.0-93-generic
 linux-image-3.13.0-93-generic
E: Sub-process /usr/bin/dpkg returned an error code (1)

Я не вполне понимаю это, так как я выполняю другое ядро:

bob@me:~$ uname -r
3.13.0-92-generic

Любые идеи, приветствовалось бы.
