How to Disable Automatic Updates in Ubuntu
Regularly updating your applications is important to protect your system from vulnerabilities and keep it updated with the latest features and security patches.
In Ubuntu, automatic updates are enabled by default and keep your system updated without needing to manually update packages. Some users prefer to have manual control over updates as it gives them the flexibility to install updates according to their preferences.
Let’s see how you may disable automatic updates in Ubuntu.
Why Disable Automatic Updates on Ubuntu?
Manually updating your systemregularly can be a time-consuming and tiresome task. Automatic update, also known as the Unattended Upgrade feature on Ubuntu makes this task easier. It automatically checks and installs security and other updates without any manual intervention.
It also has some drawbacks like it consumes bandwidth and resources which slow down your system and affect other processes, particularly during peak hours. By disabling automatic updates, you can have manual control over when and which update to run.
Furthermore, when you try to install some packages on Ubuntu while the automatic update is running in the background, you will receive an error stating “Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend.”
This is quite irritating as it does not let you install the package until the update is finished. To prevent this from happening again, the only option you have is to disable automatic updates.
