Package libnet-perl is a virtual package

[Philipp]

My source.list is:

Code:

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

and yes, I run apt-get update && apt-get upgrade

I also checked in the meantime the other servers. This error appear now on all 3 servers if I try to run apt-get install libnet-perl on those machines.
