Катастрофические отказы Центра программного обеспечения после новой установки (15.10)

При выполнении центра программного обеспечения это кратко открывается и затем shutsdown. Выполнение от терминальных урожаев:

Теперь, я думал о просто чистке python2.7 через Кв. - добираются и затем переустановка. Однако это, кажется, также хочет удалить большую часть из, ну, в общем, всего остального.

Я пытался сделать:

sudo apt-get purge software-center
sudo apt-get update
sudo apt-get install software-center

Но то же просто происходит снова.

Какие-либо идеи, как зафиксировать?

Спасибо.
