The create-site uses the deprecated --no-mariadb-socket command line argument. Using the recommended --mariadb-user-host-login-scope='%' has been tested successfully

error message: --no-mariadb-socket is DEPRECATED; use --mariadb-user-host-login-scope='%' (wildcard) or --mariadb-user-host-login-scope=, instead. The name of this option was misleading: it had nothing to do with sockets.
