For Ubuntu Desktop, after when it was upgraded from 20.04 to 22.04, when the sudo apt update command is executed arises (fixed in multiple lines):
W: http://repo.mysql.com/apt/ubuntu/dists/focal/InRelease:
Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg),
see the DEPRECATION section in apt-key(8) for details.
How to fix that? The mentioned suggested section in the message is not valuable for guidance about step by step and is need it have MySQL updated in peace in Ubuntu 22.04 as was accomplished from the beginning at 20.04.
