I guess everyone already knows that OpenOffice.org 3.0 will not be available (sad, I know) for the Intrepid Ibex (Ubuntu 8.10), because the developers did not have enough time to test it, and they will introduce it later this year. Therefore, Ubuntu 8.10 ships with OpenOffice.org 2.4.1 and, if you want to use the new and improved version, then this guide is for you! However, we will not do a fresh install of the OpenOffice suite, as we will instead only upgrade the current version in Ubuntu Intrepid.
Editor's note: Check out our brand new How to Install OpenOffice.org 3.1 on Ubuntu 9.04 tutorial.
What do I need to get started? Ubuntu 8.10 (32-bit or 64-bit), which can be downloaded from here.
OK, so... first thing, you must add the OpenOffice.org 3.0 repositories, then upgrade the installed packages. Follow the steps below!
STEP 1 - Add the OpenOffice.org 3 repositories
Go to System -> Administration -> Software Sources...
deb http://ppa.launchpad.net/openoffice-pkgs/ubuntu intrepid main
HERE and "Save Link As..." the key file on your desktop. Go to the fourth tab, "Authentication", click the "Import Key File" button, navigate to the location were you've just saved the key file (File System/home/YOURUSERNAME/Desktop) and double click it. You will immediately see a new entry called "247D1CFF 2009-01-21 Launchpad PPA for OpenOffice.org Scribblers".
STEP 2 - Update OpenOffice to version 3.0.0
When the Software Sources window will close itself, the update icon will appear in the system tray...
