I had a similar but different problem in the end:

changing the permission was not enough, there was something else:

when validating the content of the file /etc/mysql/my.cnf i get this:

!includedir /etc/mysql/conf.d/ !includedir /etc/mysql/mysql.conf.d/ 

valid that all the files exist and the first file/directory is missing, it occurred to me to proceed to comment it like this:

#!includedir /etc/mysql/conf.d/ !includedir /etc/mysql/mysql.conf.d/ 

apply the procedure again with 644 permissions and restart the server, and everything works fine now with no warnings.

I can't properly set permissions to MySQL config files
