Upgrading to Open Office 3.0 on Ubuntu

Open Office 3.0 has been released but it is not available on Ubuntu 8.04 or 8.10. Fortunately it is available on Launchpad repository. Add the following repository to your software sources:
deb http://ppa.launchpad.net/openoffice-pkgs/ppa/ubuntu hardy main

Replace hardy with intrepid if you are running Ubuntu 8.10.

Get the PGP Key from the following URL:
http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0x60D11217247D1CFF

Save the PGP Key to a text file and add it through Authentication tab and click Import Key File… on Software sources.

If you already have Open Office 2.4 you can do:
$ sudo apt-get update
$ sudo apt-get upgrade

otherwise you can install the entire office suite through:
$ sudo apt-get install openoffice.org
