Linode Forum :: View topic - iptables-persistent on Ubuntu 12.04 upgrade failing
Use modeprobe -q iptable_filter || true and modprobe -q ip6table_filter || true in /var/lib/dpkg/info/iptables-persistent.postinst when stuck with problems to update / install iptables-persistent under ubuntu 12.04 LTS. This is a workaround, proper fix arrives with iptables-persistent 0.5.6 (which has not been backported to precise pangolin, as of this writing)
