Re: MySQL Server 8.0.22 Missing sys folder database upgrade fails

[Daniel Retief]

For some reason this time when I ran the upgrade minimal option it worked:

sudo -u mysql mysqld --upgrade=MINIMAL --skip-grant-tables --skip-networking &

I was then able to log in to mysql to drop the sys schema

mysql -u root

DROP DATABASE sys;

Then restart mysql server normally to complete the full upgrade:

sudo killall mysqld

sudo service mysql start

Hope that helps someone!
