In fact  I do not need to have a running server on the machine where I install the tango-db service.
I just need to have a working server somewhere.
This is why I did not make it depends on the mysql-server erver.

It there an official way to express: having a running server available. ?

for now I just make the package failed during the installation if there is no running server.

In fact my question was more. I have a running service with mysql-server installed on my machine.

I did the upgrade and at the end I do not have a mariadb-server runingon my machine.

I thought that for Jessie -> Stretch it was expected during the upgrade to replace the mysql-server with mariadb.


Is it already available in testing or should I wait before doing this sort ofmigration test.
