Ошибки при выполнении склонный - получают обновление (Ubuntu 14.04 LTS)

Я работал

    apt-get update
    apt-get upgrade

и все шло прекрасное, пока этого не произошло:

Таким образом, я работаю:

    # free -m
             total       used       free     shared    buffers     cached

Мне, который похож на достаточную память для выполнения обновления. Затем я пробую:

На данном этапе я не уверен, чем проблема состоит в том, что я должен пытаться зафиксировать. Я был бы очень признателен, если кто-то мог бы указать на меня в правильном направлении.

Спасибо!
