Ubuntu 8.10 Intrepid Ibex didn't come with the newest version of Open Office, due to Open Office 3 not being released early enough for the developers to test it. If you don’t want to wait for the developers of Ubuntu to release Open Office 3, you can open synaptic package manager and add:
deb http://ppa.launchpad.net/openoffice-pkgs/ubuntu intrepid main
to your third party software sources. Then update. Worked like a charm for me.
