New package in repository but no upgrade

["Stefan C. Müller" <stefan@s-mueller.ch>]

Hi

I'm a bit new to the debians package system (that is, I use it for a 
long time, but I never had to care about it). Now there is something odd 
I don't understand.

It's the clamav package. On the volatile repository there's currently 
version "0.94.dfsg-1~volatile1" available. On my server there's only 
"0.93.1.dfsg-volatile1". I'd expect that a simple apt-get update/upgrade 
would get me the new one, but apt-get clames that there are no packages 
available for upgrade.

That's the lines of my sources.list:

deb http://ftp.debian.org/debian/ etch main contrib non-free
deb http://security.debian.org/ etch/updates main contrib non-free
deb http://volatile.debian.org/debian-volatile etch/volatile main 
contrib non-free

Any Ideas?

Stefan
