Package: network-manager Version: 1.0.2-2 Severity: important Tags: patch I sometimes share my WiFi connection to the Internet via Ethernet. A recent upgrade of dnsmasq-base (I think 2.72-3.1+b1 to 2.73-1) on my system broke this as dnsmasq now tries to read /etc/dnsmasq.conf when --conf-file is given without any argument, with only dnsmasq-base, this file is not present. The fix is to make it read /dev/null instead. I verified that that works by diverting the dnsmasq binary and replacing the --conf-file argument with a --conf-file=/dev/null argument.
