I am running Ubuntu Server 9.0 solely to serve FLAC audio files to my Squeezebox devices. If I do:

sudo apt-get install squeezeboxserver

I get the following:

Err http://debian.slimdevices.com testing/main squeezeboxserver 7.5.1~30695 404 Not Found

I was getting this after apt-get upgrade so I did a remove --purge squeezeboxserver to get rid of the version that was on there and then tried installing again but still got the 404 Not Found.

Now I've got no squeezeboxserver installed at all! How do I get it back on please?
