package mariadb-server-5.5 fail by design is users choose to NOT upgrade from MySQL - actual error is unclear text as users don't understand what the dialog is about

I ran a routine software update and was asked if I really wanted to upgrade from MySql. I unticked the default update and pressed "Forward". The system then reported a problem.

This is be design - if you untick the default and thus abort the migration, then the installation will fail.

I am sure this issue is a duplicate of another message with a extensive discussion but I cannot find it right now. Please somebody mark this as a duplicate if you find the older bug report with the same case.
