2021-04-30 1:42:07 140285079196800 [ERROR] mysqld: Event Scheduler: An error occurred when initializing system tables. Disabling the Event Scheduler.
Fix by starting the database with –skip-grant-tables options
mysqld --skip-grant-tables
Open new terminal window and run
mysql_upgrade -u root -p
This should upgrade the tables and you can try starting the DB with systemctl command again.
However you might run into this issue.
Tested on
- Debian 9, 10
