I have Ubuntu 20.04 installed under Windows Subsystem for Linux (WSL).
Below are the steps to upgrade Ubuntu to 22.04 Jammy Jellyfish (so that that I can enjoy my python3.10).
$ sudo apt update
$ sudo apt upgrade
$ sudo apt dist-upgrade
$ sudo apt autoremove
$ sudo apt install update-manager-core
$ sudo do-release-upgrade
Follow by a couple of 'y'
The whole process took around 2 hours to finish.
