sources.list help

[Dave Stevens <geek@uniserve.com>]

I have a friend with a new debian amd-64 install. He has unrar-free but it 
won't open RAR 3.0 files. It looks like it would be worthwhile to try unrar 
but I am not able to get appropriate access for synaptic.

I went to:
http://packages.debian.org/sid/unrar/amd64/download

and tried adding a line to /etc/apt/sources.list as suggested at that page but 
get error warnings when starting synaptic. The net effect is that searching 
for unrar gives only the already installed unrar-free. I have the .deb 
package for unrar but installing it fails due to a dependency error.

Can someone point me to a tutorial or explain how to get better information 
about the problem? This is what I got from uname:

roger@debianroger:~$ uname -a
Linux debianroger 2.6.18-5-amd64 #1 SMP Tue Oct 2 20:37:02 UTC 2007 x86_64 
GNU/Linux

Thanks very much.

Dave
