LGTM, with some nits.

One additional note is to possibly add a warning label stating that the mysql connector is only available on that repository for Debian 12 (Bookworm) and 11 (Bullseye); 13 (Trixie) and 10 (Buster) do not appear to have these available; http://repo.mysql.com/apt/debian/dists/ (under <distro>/mysql-tools/binary-amd64/Packages)

thanks @DaanHoogland @ShadowJonathan for the review !

I made some changes as per your suggestions.
please let me know if you have any other suggestion.

Possibly only the warning about the repo being supported for debian 11 and 12, but that's not entirely required at this point.

I see this got merged into 4.20, doesn't this also need to get ported to main, .21 and .22?

It will be forward-merged into 4.22 and main
(but not 4.21 which is not maintained)
