Instructions

Warning:Disabling automatic updates comes with a security risk. Once automatic updates are disabled, use $ sudo apt update and $ sudo apt upgrade to keep your system updated manually.

There are some situations when you may want to disable automatic updates. For example if you receive these error messages:
Reading package lists... Done
E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/
The above is a result of a triggered automatic updates procedure where apt locked down the /var/lib/apt/lists/lock file, thus the administrator is prevented from installing new packages and is forced to wait until the automatic updates refresh cycle is completed.

Disable Automatic Updates from Command Line

Edit /etc/apt/apt.conf.d/20auto-upgrades to disable automatic updates from the command line:
$ sudo nano /etc/apt/apt.conf.d/20auto-upgrades
Once you have the file opened, switch off the Update-Package-Lists directive from 1 to 0 as shown below on Line 1:

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