Follow these easy steps to disable automatic updates on Ubuntu 20.04 Focal Fossa 🥳
Privileged access to your Ubuntu System as root or via sudo command is required 🔓

Conventions
  • # - requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command
  • $ - requires given linux commands to be executed as a regular non-privileged user
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:
Code:
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:
Bash:
$ 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:
Rich (BB code):
APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Unattended-Upgrade "1";

This tutorial was created based on Ubuntu 18.04 Bionic Weaver, and it should work on 20.04 Focal Fossa too 👍
