If you would like to install this latest version in Ubuntu, go to System > Administration > Software Sources, Third Party Software tab, click "Add" and add these repositories (Jaunty only!)
deb http://ppa.launchpad.net/bugbear5/ooo-jaunty/ubuntu jaunty main
Then copy the following code a terminal, to import the GPG key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EC4751ED
Now all you have to do is:
sudo apt-get update && sudo apt-get dist-upgrade
Update: the openoffice-pkgs maintainer has removed all the OpenOffice packages (that was the only PPA with OOo packages for Ubuntu Intrepid and Hardy!). I have found another PPA but there are only packages for Ubuntu Jaunty Jackalope (OpenOffice 3.1.1).
