The thing is, this error in and of itself is not a problem, it's just traces of what NetworkManager is doing, to start dnsmasq on boot. The fact that this message is showing is not a bug.
However, if you don't get nameservers properly set (ie. Firefox or Chrome can't resolve web addresses), then I'd like you to please file your own bug so we can get to the bottom of it. Use 'ubuntu-bug network- manager' to do so, so all the necessary information will be there to debug the problems. This isn't an issue with dnsmasq itself or dnsmasq-base (the latter being more likely the package installed on your system). Please don't purge and reinstall these packages unless requested by a developer: it's not likely to change much. -- 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/1048430 Title: "dnsmasq not available on the bus" Status in “network-manager” package in Ubuntu: Incomplete Bug description: Dnsmasq seems to be having some issues.
