There is also a couple lines of code in the config file /etc/apt/apt.conf.d
that may need to be commented out. I believe this config file allows
automatic updates and rebooting of your system to be configured. I am not an
expert in this area so I may be wrong.
I found this info while doing a search: Setting up Automatic Updates for
Ubuntu
(http://robpickering.com/2012/06/setting-up-automatic-updates-for-ubuntu-893).
My Trisquel 7 file system is setup the same way as this article talks about.
Hope this helps.
