Introduction

It’s April 21, 2022 and the next release of Ubuntu LTS has been released to version 22.04 (Jammy). In this post we’ll cover how to upgrade your 20.04 (Focal) to 22.04 (Jammy).

The Process

First, make sure your current Ubuntu Linux system is up to date. This will help to ensure that the difference between packages is as small as possible. Execute the below commands:

Check for Updates, upgrade any packages and check system for dist upgrade

$ sudo apt update

Ubuntu apt Update

$ sudo apt upgrade -y
$ sudo apt dist-upgrade

Apt Dist-upgrade

 

Next, you should remove all no longer required packages from your system:

$ sudo apt autoremove

apt autoremove

Next, install the update-manager-core package with apt if it is not installed already

$ sudo apt install update-manager-core

aptupgrademanager

When that finishes, run the Ubuntu upgrade utility and start the upgrade!

$ sudo do-release-upgrade -d

You will be asked if you’re sure that you want to upgrade. After reading the text in your terminal, type y and press enter to begin the upgrade to Ubuntu 22.04 Jammy Jellyfish.
