sudo apt-get install alien

Grab yourself the Odf converter from http://download.go-oo.org/red-carpet/ooo-680/sled-10-sp-i586/
~odf-converter-1.1-7.i586.rpm

Now lets convert it like this:

alien -ct odf-converter-1.0.0-5.i586.rpm

You will end up with a .tgz version

Extract it to a directory, then go into it.

Now its time to copy a few files to allow us to open up our .docx file./
