How to Upgrade From Ubuntu 21.04 Desktop to Ubuntu 21.10:

Before getting started, it’s always recommended to backup important data and switch to open-source driver via “Additional Drivers” utility. Also, disable third-party PPAs via “Software & Updates -> Other Software”. And it’s better to purge Ubuntu PPAs that contains updated graphics & multi-media libraries, e.g, FFmpeg, Mesa.

1.) First, search for and open “Software Updater” utility and install all available updates. And restart your computer if required.

2.) Press Ctrl+Alt+T on keyboard, and run command to launch the Software Updater with checking system upgrade:

update-manager -c

It will open up ‘Software Updater’ and indicate that Ubuntu 21.10 is available for upgrade. Don’t see the prompt? Try opening “Software & Updates” and select notify me for any version under ‘Updates’ tab.

3.) After clicking on “Upgrade” button, it will bring up the ‘Impish Indri Release Note’ dialog.

4.) Click “Upgrade” again and it opens the “Distribution Upgrade” wizard indicates the process.

5.) After ‘Preparing to upgrade’ and ‘Setting new software channels’, it will ask for confirm again for upgrading the system.

Now, it starts downloading the new packages and installing the updates! And, it will ask for confirm to clean up obsolete packages. After all, restart computer when it indicates restart to complete upgrade.

How to Upgrade From Ubuntu 21.04 Server to Ubuntu 21.10:

To upgrade Ubuntu Server, firstly connect to command console, and install the update-manager-core package via command:

sudo apt install update-manager-core

Make sure the Prompt line in /etc/update-manager/release-upgrades is set to normal via command:

cat /etc/update-manager/release-upgrades |grep Prompt

If the value if not normal, you need to edit the file and change it.

Finally, start the upgrade tool and follow onscreen instructions via command:
