Fixing "debian_sys_maint" Errors

If you work with MySQL in Debian, you might come across this problem after restoring a backup. When you boot your computer and in the system logs, you will see a permission denied error from debian_sys_maint@localhost keeps cropping up.

To fix this problem, simply set the password for the MySQL user to match the password stored in the /etc/mysql/debian.cnf file. Simple but effective!
