I am trying to do the automatic upgrade from 2.9.1 to 2.9.2. I am running WP on ubuntu on linode using apache. All the public html file are owned by www-data. When I click on "Upgrade Automatically" I see a message that says "Unpacking the update." then nothing happens.
I've noticed that a file called worpdress-2.tmp is created in the wp-content directory. Would like to get this working.
