I think I found the solution: when upgrading from the previous version and if you keep your original /etc/mysql/mysql.conf.d/mysqld.cnf then you most likely have an option in there which is called "myisam-recover". If you rename that to "myisam-recover-option", then you should be able to restart the mysql service.
