The next version of Debian will come ...
Here is one issue we'll have to look at, but there might be more ...
In #2792723: Install fails on enabling hosting-queued daemon vanilla 16.04 LTS Server ergonlogic mentioned:
Note that on Stretch, the mysql-server and mysql-client packages appear to have been replaced by default-mysql-server and default-mysql-client. Note that the former actually installs MariaDB, which, in turn, triggers #2770819: Install fails on MariaDB 10 without password (new default). Setting an alternative db user (e.g., 'aegir_root') with proper permissions allowed installation to proceed.
