FreeRadius: Failed to open file '/etc/freeradius/sql/mysql/schema.sql', error: 13

I’m having the following error message when trying to setup FreeRadius on Ubuntu.
I’ve been trying to change different owners on the file (/etc/freeradius/sql/mysql/schema.sql) but doesn’t work too.
Please let me know how to fix this issue.
