Ok so the original fail is invalid, this was a local config issue. Will
close this bug report.

Not sure about the dependency question. However, the reaosn the package
is not reinstalling the config file after you removed it is that this is
considered an intentional action by the administrator, and so dpkg will not
reverse it.

To get around it, you need to purge the original mysql-common package

dpkg --purge mysql-common

This is a red herring.

No, you should purge mysql-common, and then install again. That should restore
the default my.cnf to /etc/mysql.
