Wordpress permission fix

When I upgrade the wordpress, it shows the error

This is usually due to inconsistent file permissions.: wp-admin/includes/update-core.php

So I reset all the permission for the files:

cd /var/www/wordpress
sudo find . -type f -exec chmod 664 {} +
sudo find . -type d -exec chmod 775 {} +

And try the upgrade again, it works.
