Setup
Edit:
/etc/apt/sources.list
My sources.list contains:
#
# deb cdrom:[Debian GNU/Linux 4.0 r0 _Etch_ - Official i386 NETINST Binary-1 20070407-11:29]/ etch contrib main
# deb cdrom:[Debian GNU/Linux 4.0 r0 _Etch_ - Official i386 NETINST Binary-1 20070407-11:29]/ etch contrib main

deb-src http://security.debian.org/ etch/updates main contrib
deb http://ftp2.de.debian.org/debian/ etch main
