The autopkgtests started failing shortly after mariadb 11.4 was
uploaded. In the 11.4 release notes it indicates that TLS will now be
enabled by default[0].

Looking at the mariadb logs after the failed autopkgtests, I see
this:

Jul 08 16:09:27 autopkgtest-lxd-wuacks mariadbd[5914]: 2025-07-08 16:09:27 3 [Warning] Aborted connection 3 to db: 'unconnected' user: 'unauthenticated' host: 'localhost' (This connection closed normally without authentication)
Jul 08 16:09:27 autopkgtest-lxd-wuacks debian-start[5944]: ERROR 2026 (HY000): TLS/SSL error: SSL is required, but the server does not support it

Running `echo '\s' | mysql --ssl=0` works:

--------------
mysql from 11.8.2-MariaDB, client 15.2 for debian-linux-gnu (x86_64) using EditLine wrapper
