There's other probably far simpler (and safer) workarounds. What's your configuration for the dnsmasq like?
Upstream mentions some configurations at the dnsmasq level that are very relevant for this particular case: in /etc/dnsmasq.conf: #except-interface= # Or which to listen on by address (remember to include 127.0.0.1 if # you use this.) #listen-address= The problem is that listen-address probably shouldn't contain 127.0.0.1 if dnsmasq is meant to be used to resolve things for ltsp clients; also, except-interface=lo may be a good idea here to avoid listening on the loopback interface. That way both instances should start fine. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/959037 Title: Don't start local resolver if a DNS server is installed Status in “network-manager” package in Ubuntu: Triaged Bug description: As described in https://blueprints.launchpad.net/ubuntu/+spec/foundations-p-dns- resolving, network manager now starts a dnsmasq instance for local DNS resolving. That breaks the default bind9 and dnsmasq installations, for people that actually want to install a DNS server. Having to manually comment out "#dns=dnsmasq" in /etc/NetworkManager/NetworkManager.conf doesn't sound good, and if it stays that way, it should be moved to the bind9 and dnsmasq postinst scripts. Please make network-manager smarter so that it checks if bind9 or dnsmasq are installed, so that it doesn't start the local resolver in that case.
