After I update mysql I usually run:

$ mysqlcheck --all-databases --check-upgrade -u root -p

and it completes fine.


However, if I try 'mysql_upgrade -u root --password=XXXXXX' it fails
at the end like so:

$ mysql_upgrade -v -h localhost -u root --password=XXXXXX

Could not create the upgrade info file

errno: 13


The strange thing is that running the mysql_fix_privilege_tables
command by hand succeeds!

$ mysql_fix_privilege_tables -v -u root --password=XXXXXX
This script updates all the mysql privilege tables to be usable by
the current version of MySQL

done


I'm not sure I understand why this happens. I even created the file
/var/lib/mysql/mysql_upgrade_info by hand and chowned it to
mysql:mysql, but still comes up with the same error. The file stays
empty:

ls -la /var/lib/mysql/mysql_upgrade_info
-rw-rw---- 1 mysql mysql 0 May 12 01:03 /var/lib/mysql/mysql_upgrade_info

Any ideas?
