So – installing OOo 3.0 on an Ubuntu AMD64 may not be as trivial as it seems.

In order to get it running, I had to go through a “couple” of steps:

• Remove the previous installation of OOo:

  > sudo apt-get remove open-office.org-core

• Download OOo 3.0 from here and choose the Linux DEB version
• Open a terminal and cd to the folder where you saved the downloaded .tar.gz file: OOo_3.0.0_LinuxIntel_install_en-US_deb.tar.gz
• Extract the contents of the .tar.gz via:

  > tar xvzf OOo_3.0.0_LinuxIntel_install_en-US_deb.tar.gz

• Go to the DEBS foloder

  > cd OOO300_m9_native_packed-1_en-US.9358/DEBS/

•  In order to install i386 on AMD6:

  > sudo dpkg -i --force-architecture *.deb

• Navigate to the desktop integration folder:

  > cd ./desktop-integration/

• Install desktop integration (ie. menu support)

  > sudo dpkg -i --force-architecture *.deb

• Done!

Happy running OOo 3.0! (and you can kind of open Office 2007 file formats too – I haven’t seen yet a good pptx in OOo 3.0 – but who knows – maybe one day!)
