How to use the unstable repositories
 

I've recently installed Debian testing, and I want to upgrade my software, because testing uses some quite old versions of openoffice, gnome, etc. So I was wondering how can I modify my sources.list file to use the debian unstable repositories, here is my sources.list file:

# deb cdrom:[Debian GNU/Linux testing _Etch_ - Official Snapshot i386 Binary-1 (20051111)]/ etch contrib main

deb http://mirrors.kernel.org/debian/ testing main
deb-src http://mirrors.kernel.org/debian/ testing main

deb http://security.debian.org/ testing/updates main

deb http://mirrors.kernel.org/debian/ testing main
deb-src http://mirrors.kernel.org/debian/ testing main

deb http://security.debian.org/ testing/updates main

All you need to do is edit the sources.list (as root) with your favorite text editor and change the word "testing" to "unstable" or "sid" (the name of the unstable branch).

Then from the root CLI type apt-get update && apt-get dist-upgrade. It'll ask you some questions and you should be on your way. Everything should go okay.

I assume the duplicate repositories listed are just a typo in this thread...
