How to Disable Automatic Updates in Ubuntu

Automatic updates should be convenient, and it should keep your system secure. But they can also be annoying, and sometimes it’d be better if the system just let the user decide when to update. In this guide, we’ll go through the steps to disable automatic updates and unattended upgrades in Ubuntu Linux.

Automatic updates are usually something you don’t want to disable. They include important security and feature updates, and the user doesn’t need to remember to retrieve them manually. You should only disable automatic updates if you have a unique case and are not a casual Linux user.

The biggest cases for disabling these updates may be that they happen at inopportune times, or the annoyance of trying to install a package when Ubuntu is trying to retrieve updates and gives you the “could not get lock” error.
