Ubuntu - Automatic Security Updates


If you're like me, you probably whack up a few ubuntu VPS systems running ubuntu because it's quick and easy, but know that you aren't going to be constantly checking them to update/upgrade them. If this is the case, then you may want to consider setting up automatic security updates on these systems.


The following tutorial has been tested on Ubuntu 12.04 and 14.04


Run the following commands:

sudo apt-get install unattended-upgrades -y
sudo dpkg-reconfigure unattended-upgrades

At the prompt shown below, make sure to highlight 'yes' and hit enter/return.

Additional Configuration

. If enabling email alerts, don't forget to install the postfix package!
