Ubuntu Package Missing GPG Key

So, I got the repos to update from Open Office 2.4 to Open Office 3.0

deb http://ppa.launchpad.net/openoffice-pkgs/ubuntu intrepid main

which I added to my /etc/apt/sources.lst

However I kept getting the NO GPG key authentication error when I was trying

sudo apt-get upgrade

I stumbled onto this GEM. Thanks to lvlo.

Firstly run:

gpg --keyserver keyserver.ubuntu.com --recv-keys $KEY

then run:

gpg --export --armor $KEY | sudo apt-key add -

$KEY is the value of the package you are not authenticated for.

For Open Office 3.0 I got 60D11217247D1CFF

This worked for me... Hopefully it works for you also.
