Hi, Got a tip from backports list to check with you guys too about this problem.
When I do Wheezy (i386) preseed installation with backports: d-i apt-setup/local0/repository string http://ftp.fi.debian.org/debian wheezy-backports main d-i apt-setup/local0/comment string Debian Backports repository installation goes ok, but aftert reboot network is not working. I made 2 installations (no GUI): first one does not have the backports in the preseed at all --> network ok (got "dpkg -l" output to file). second one does have backports in the preseed --> network NOT ok (got "dpkg -l" output to file too). When I diff the "dpkg -l" files "diff no-bp.txt bp.txt": 76c76 < ii ifupdown 0.7.8 i386 high level tools to configure network interfaces --- > rc ifupdown 0.7.8 i386 high level tools to configure network interfaces 83c83,84 < ii iproute 20120521-3+b3 i386 networking and traffic control tools --- > rc iproute 20120521-3+b3 i386 networking and traffic control tools > ii iproute2 3.15.0-2~bpo70+1 i386 networking and traffic control tools 86c87 < ii isc-dhcp-client 4.2.2.dfsg.1-5+deb70u6 i386 ISC DHCP client --- > rc isc-dhcp-client 4.2.2.dfsg.1-5+deb70u6 i386 ISC DHCP client 100a102 > ii libatm1:i386 1:2.5.1-1.5 i386 shared library for ATM (Asynchronous Transfer Mode) Why is iproute2 installed from backports? Guess that is our problem here.
