Ubuntu 22.04 is officially released on 22 April 2022 and available on all cloud platforms also. Here you are going to upgrade your system or server from Ubuntu 20.04 to Ubuntu 22.04. If you are running Ubuntu 18.04, you need to first upgrade to Ubuntu 20.04 and then finally upgrade to 22.04 LTS.
In this guide you are going to learn how to clean up your Ubuntu 20.04 server or system’s unused packages, old kernels, journal logs, apt cache and then upgrade to 22.04 LTS in simple steps.
This setup is tested on Google Cloud Platform VM running Ubuntu 20.04. So it should work well on other servers and other systems also.

- Root access to your system or server or a user with sudo privileges.
- Create a backup of your files (just for a precaution).
