How to Install Security Updates in Ubuntu 20.04

An essential part of using any operating system is to check for security updates from time to time. It can be difficult to keep track of security updates all the time. One of the easiest ways to keep your Ubuntu system secure is by upgrading your software packages. New versions add the latest features available, and system security is increased by updating programs frequently.

This guide shows you how to install security updates in Ubuntu 20.04, which will be performed by upgrading security packages.

There are two primary methods for upgrading the software to minimize the vulnerability of security issues:

  • Update Ubuntu via the Command-Line
  • Update Ubuntu

Method 1: Update Ubuntu via the Command-Line

Updating Ubuntu using the command line gives you more clarity and authority over the process. Open your terminal and issue the following command to update the packages:

$ sudo apt update

To get a list of packages that are due for an update, enter the following command:

$ apt list --upgradable

Now, all the packages can be updated using the following command, which will complete all updates of the packages that require updates. After you enter the command listed below, your operating system will be upgraded successfully:

$ sudo apt upgrade

There will always be some software packages in the system that depend on each other to function properly.

These packages can be updated using the “dist-upgrade” command mentioned below. Type the command in the terminal to get an update:

$ sudo apt dist-upgrade

Unused packages that are no longer needed can be removed by executing the following command:

$ sudo apt autoremove
