Firstly, go to the OpenOffice website: http://download.openoffice.org/ and download the Linux .deb file.
1 – Once you have done that, extract the .deb file,
Then you’ll see a file called OOO320_m12_native_packed-1_en-US.9483
2 – You can remove the existing version of OpenOffice if you wish with this command:
sudo apt-get remove openoffice*.*
3 – Copy and paste OOO320_m12_native_packed-1_en-US.9483 onto the desktop then open Terminal and paste this command:
sudo dpkg -i ~/Desktop/OOO320_m12_native_packed-1_en-US.9483/DEBS/*.deb
4 – Then paste this command:
sudo dpkg -i ~/Desktop/OOO320_m12_native_packed-1_en-US.9483/DEBS/desktop-integration/openoffice.org3.2-debian-menus_3.2-9472_all.deb
Once you’ve done that you’ll find OpenOffice 3.2 in Office.
