Installing OOo3.3 on Ubuntu, Debian.

Here is a method for all Debian-based distros :
1. Remove all the packages from the installed version
Go to Synaptic or your package manager and mark all the openoffice.org packages installed to be removed (there is the string ubuntu in their version number). This is mandatory for your first upgrade of the distro delivered OOo version.
Note: don’t use the Ubuntu Software Center to remove OOo because it seems that some packages are left and conflict with the install with official debs.
Restart The System.
2. Download the tarball (.tar.gz file) from the official OOo web site
See here : http://download.openoffice.org/other.html. Select the Linux DEB version!

3. Extract the tarball in your home directory (or any other directory you want)
Either do that with your file browser and your archive manager (usually available in the context menu) or open a terminal (you should be directly in your home directory) and :

:~$tar -vxzf filename

4. Install the created .debs
:~$cd  OOo_inst_folder/DEBS
:~$sudo dpkg -i *.deb

5.Update the Applications menu

Go to the desktop integration subfolder.

:~$cd  desktop-integration

6.Run again the previous installation command.

:~$sudo dpkg -i *.deb
