Updating Ubuntu 16.04 to 20.04
Is there, anywhere on the internet, a reliable step-by-step guide on how to upgrade from Ubuntu 16.04 to 20.04? Apparently it has to be done via 18.04. I have updated the current 16.04 system by:
sudo ufw allow 1022/tcp
sudo apt update && sudo apt upgrade

I guess that is why the system upgrade fails:
- sudo do-release-upgrade
gives the message:
Please install all available updates for your release before upgrading.
Thanks for any help!
