[debian-mysql] Bug#914188: Bug#914188: mariadb-server: Upgrade faild due to 'unknown variable': 'server_audit_file_path=/path/to/audit.log'

[Faustin Lammler]

Marc,
I am not able to reproduce this.

Here are my steps:
- installation of mariadb-server-10.1_10.1.26-0+deb9u1;
- load and activation of the audit plugin:
	$ cat /etc/mysql/my.cnf | grep -v ^#
	[mysqld]

	plugin_load=server_audit=server_audit.so
	server_audit_file_path=/var/log/mysql/mariadb_server_audit.log
	server_audit_logging=ON

	[client-server]

	!includedir /etc/mysql/conf.d/
	!includedir /etc/mysql/mariadb.conf.d/
- restart mariadb and check that plugin is loaded and activated;
- upgrade to mariadb-server-10.1_10.1.37-0+deb9u1;
	$ sudo apt-get dist-upgrade
- check that audit plugin is still activated;

Can you give me the content of you /etc/mysql/my.cnf file?
Is it possible that on your system a previous version of mariadb/mysql
was installed (before 10.1.26)?
