Are you upgrading MySQL, and seeing this?

$ mysql_upgrade
Looking for 'mysql' as: mysql
Looking for 'mysqlcheck' as: mysqlcheck
Running 'mysqlcheck'...
....
Could not create the upgrade info file
   '/usr/local/mysql/data/mysql_upgrade_info'
in the MySQL Servers datadir, errno: 13

Solution — run the script as root (so you’ll have permission to write to mysql_upgrade_info).
