OpenOffice has released the latest version of their Office Suite. Here’s how to Install OpenOffice 2.3.0 on Ubuntu.

Deb Installer:

If you’re looking installing from the deb package, here are the instructions once you download the deb file from this link:

sudo apt-get remove openoffice*
tar xzvf OOo_2.3.0_LinuxIntel_install_en-US_deb.tar.gz
cd OOo_2.3.0_LinuxIntel_install_en-US_deb.tar.gz
cd DEBS/
sudo dpkg -i *.deb
cd desktop-integration/
sudo dpkg -i *.deb
sudo ln -s /opt/openoffice.org-2.3/programs/soffice /usr/local/bin


RPM Installation in Ubuntu

If you’ve already downloaded the RPM version and don’t want to bother re-downloading the deb package, here’s what you do:

Once you’ve got the package downloaded, run the following commands in your terminal :
sudo apt-get install alien
sudo apt-get remove openoffice*
tar xzvf OOo_2.3.0_LinuxIntel_install_en-US.tar.gz
cd OOG680_m5_native_packed-1_en-US.9221/
cd RPMS/
sudo alien --scripts --keep-version *.rpm
sudo dpkg -i *.deb
cd desktop-integration/
sudo dpkg -i *.deb
sudo ln -s /opt/openoffice.org-2.3/programs/soffice /usr/local/bin
