One of the easiest ways to protect your Ubuntu systems is by keeping up to date software on them. Therefore applying updates frequently is an important part of maintaining secure systems. In this article, we will show how to install security updates in Ubuntu and Linux Mint systems.

Intalling Security Updates on Ubuntu

If your system has the update-notifier-common package installed, Ubuntu will alert you about pending updates via the message of the day (motd) upon console or remote login.

Once you have logged into your Ubuntu system, you can check for new updates using the following apt command.

$ sudo apt update
