Installing OpenOffice.org 3.0 on Debian Lenny (stable)

There is no OpenOffice.org 3.0 in lenny-backports till now and I need it! So, I grabbed it from sid (unstable). This discussion helped me a lot:
http://www.linuxquestions.org/questions/debian-26/openoffice-3-in-debian-lenny-679610/

In short, you need to

1. add to your repositories (/etc/apt/sources.list)
   

   deb http://www.backports.org/debian lenny-backports main contrib non-free

2. Also add to your repositories
   

   deb http://http.us.debian.org/debian sid main

3. To stay with the stable and not install packages from unstable by default, we need to add the following to /etc/apt/apt.conf APT::Default-Release "stable";
   
   
4. Then do aptitude install openoffice.org/unstable

Voila! Hope it does not break your system!

UPDATE: OpenOffice.org is now available in Lenny-backports. Now you do not need step 2. So, instead type aptitude install openoffice.org/lenny-backports
