Unattended-Upgrades with Debian Jessie 8

The package "unattended-upgrades" comes pretty handy for automatic security updates. Nevertheless there are a couple of settings you have to be aware of.

First you have to install the package "unattended-upgrades" of course. It installs a binary called "unattended-upgrades" which is run daily by the apt cron job:
/etc/cron.daily/apt

After that you have to not only enable unattended-upgrades but also the periodic update of your packages . Create the following file:

/etc/apt/apt.conf.d/02periodic

APT::Periodic::Unattended-Upgrade "1";
APT::Periodic::Update-Package-Lists "1";

"1" means updating and running unattended-upgrades every day.

There are a couple of more options. Take a look at the following files:

/etc/cron.daily/apt
/etc/apt/apt.conf.d/50unattended-upgrades
