Докеру не удается установить правильно (или работать) на Ubuntu 16.04

Ниже терминальный вывод, когда я следовал руководству от digitalocean в https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-16-04

Это использует репозитории докера, так теоретически это должно работать, но не делает.

Это, кажется, dpkg ошибка, когда это пытается настроить.

Существует ли способ диагностировать эту ошибку, таким образом, это устанавливает правильно?
