Hello,
I have a X230 with Ubuntu 20.04 OEM currently installed, and I have to perform an upgrade to 22.04.
Can I do it by using the integrated Software Updater, like described here https://ubuntu.com/tutorials/upgrading-ubuntu-desktop#2-launch-the-software-updater, or do I have to download an ISO from here https://www.nitrokey.com/files/ci/ubuntu/ and make a clean install, and then restore my Timeshift backup ?
Thanks in advance for your feedback
