Introduction

When running a server automatic updates can be a dangerous affair.  When I setup my servers I disable this feature in Ubuntu.

The Fix

Edit /etc/apt/apt.conf.d/20auto-upgrades
> sudo nano -w /etc/apt/apt.conf.d/20auto-upgrades

Change the file to the follosing

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "0";

Now reboot the system.
> sudo reboot

Conclution

A quick change to a file.  A reboot and its all done.
