Hi,

I'm using your role with Debian jessie 8.7.

Currently I get a 404 http-response when ansible is try to install apt package.

I would suggest to add an update_cache: yes
Belongs to pull-request #37

@robinlehrmann - Please see #33 — basically we pulled that out of this role, and the intention is that you'd add the task on your playbook level itself (maybe in pre_tasks) instead.
