Prerequisites to Upgrade to Ubuntu 22.04

The upgrade action must be performed as a superuser. You must be logged in as root or as a user with sudo rights to use this feature. Superuser capabilities are usually granted by default to the user created when Ubuntu is first installed.

From Ubuntu 20.04 or Ubuntu 21.10, you can upgrade directly to version 22.04. If you're using an older version of Ubuntu, you'll need to upgrade to Ubuntu 20.04 or 21.10.

Make sure your Internet connection is up and running.

Backup Your Data

First and foremost, make a backup of your data before beginning a large operating system upgrade. If you're running Ubuntu on a virtual machine, you should take a full system snapshot, so you can immediately recover your machine if something goes wrong with the update.

Update Currently Installed Packages

It is advised that you update all of your currently installed packages to the most recent versions before beginning the release upgrade.

Packages that have been marked as held back cannot be installed, upgraded, or uninstalled automatically. This could cause problems during the upgrading. Run the following command to see if any packages are being held back on your system:

sudo apt-mark showhold

There are no packages held back if the output is empty.

If there are any packages on hold, you should unhold them with the following command:

sudo apt-mark unhold package_name

Update all installed packages and refresh the apt list:

sudo apt update
sudo apt upgrade

Upgrade your system:

sudo apt full-upgrade

Some currently installed packages may be removed by apt full-upgrade, preventing the system from being upgraded as a whole.

Remove any obsolete kernels and automated dependencies that are no longer required by any package:

sudo apt --purge autoremove

Upgrade to Ubuntu 22.04 LTS (Jammy Jellyfish)

Upgrading to the most recent Ubuntu version is a simple process. You can use the GUI update tool or do-release-upgrade to upgrade from the command line.

We'll update using the command line, which should work on both desktop and server computers.

Most Ubuntu systems include with the "update-manager-core" package, which includes do-release-upgrade. If it isn't already installed on your machine, use the following commands to do so:

sudo apt install update-manager-core

If you're upgrading through ssh and your system has a firewall, you'll need to temporarily open port 1022:

sudo iptables -I INPUT -p tcp --dport 1022 -j ACCEPT

Enter the following information to begin the upgrade process:

sudo do-release-upgrade

All third-party repositories will be disabled, and the apt list will be changed to point to the "jammy" repositories by the do-release-upgrade command. You will be asked to confirm that you wish to proceed with the upgrading many times. When prompted if you want the services to be resumed automatically during the update, select y.

Various questions will be asked during the upgrading process, such as whether you want to keep an existing configuration file or install the package maintainer's version. It should be safe to type Y if you haven't made any special changes to the file. Otherwise, it's best to stick with the current setup. Before making a decision, thoroughly read the questions.

The upgrade takes place within a GNU screen session, and it will immediately reconnect if the connection is lost.

Depending on the quantity of updates and your Internet speed, the entire procedure may take some time.

The update application will ask you if you wish to uninstall the obsolete software after the new packages have been installed. If you're not sure, type d and look through the list of deprecated packages. Entering y and removing all obsolete packages is generally safe.

You'll be asked to reboot your machine once the upgrading procedure is finished, if everything went correctly. Type y to continue:

Output

System upgrade is complete.

Restart required

To finish the upgrade, a restart is required.
If you select 'y' the system will be restarted.

Continue [yN] y

Confirm the Upgrade

Wait a few moments for your system to boot up before logging in.

You will be met with a new graphical boot splash and login screen if you are a desktop user.

You may also use the following command to see which Ubuntu Version you're running:

lsb_release -a

Distributor ID:	Ubuntu
Description:	Ubuntu 22.04 LTS
