Learn how to upgrade to Ubuntu 22.04 from Ubuntu 20.04 or Ubuntu 21.10 in this guide. Upgrading to Ubuntu 22.04 LTS 'Jammy Jellyfish' is quick and easy.

Then again, if you are on Ubuntu 21.10 or 20.04 LTS an early taste is just a sudo do-release-upgrade -d away.

The only bug I have experienced is having to log in twice, the first time seems to fail after 3 seconds no matter what.
