[Koha] After Koha update and auto_increment_fix database won't start

[Mason James]

try adding to line to the following file... then restart
   /etc/mysql/mariadb.conf.d/50-server.cnf

> I followed the instructions in https://wiki.koha-community.org/wiki/DBMS_auto_increment_fix#Current_Solution
> Probably I did something wrong when I added the line
>       init-file=/var/lib/mysql/init-file_koha_fix.sql
> at /etc/mysql/my.cnf. The instruction says to find the [mysqld] section in the file, but in my my.cnf file there is only one line that says:
> !includedir /etc/mysql/conf.d
