OpenOffice 3.1 has been released with some cool features that we so long waited. The way to install it, is pretty much the same when you installed OpenOffice 3.0. So to start, I have Ubuntu 9.04 as my OS, other Debian-based OSs and Ubuntu derivatives are applicable too.
Uninstall your previous version.12sudo apt-get remove --purge openoffice.org-*rm -rf /home/[yourUsername]/.openoffice.org
Of course, download OpenOffice 3.1 first (in my case
Next, launch the terminal and extract the package.1tar -xvzf OOo_3.1.0_LinuxIntel_install_en-US_deb.tar.gz
Now, enter to its directory by issuing the following commands.1cd OOO310_m11_native_packed-4_en-US.9399/DEBS/
Install all the packages inside.1sudo dpkg -i *.deb
Next, install the shortcuts.12cd desktop-integrationsudo dpkg -i *.deb
Now you should have OpenOffice ready in your menu.
These are the steps I made for me to complete my installation without conflict. Of course there are other methods like from the repository, but yesterday when I installed mine, the update was still not uploaded. Also, you may notice that the splash screen is still on OpenOffice 3.0, its normal, maybe they just forgot to change it.
