I'm afraid I don't know how to help debug this either. At the moment, I don't think it's clear whether this is a bug or not, as opposed to some kind of local configuration issue, especially as we seem to have only one report of this problem.
If you can provide steps that somebody else can use to reproduce, please do so. Otherwise, I'm afraid that it doesn't seem likely that this report can make further progress, so I'm marking it Incomplete for now to make this clear. To get community help, there are pointers at http://www.ubuntu.com/support/community - though it looks like you know about these already. ** Changed in: dnsmasq (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1642973 Title: DNS stops working when changing networks Status in dnsmasq package in Ubuntu: Incomplete Bug description: Since upgrading to 16.10 I am having frequent DNS failures. It usually happens when I change networks and after resume from suspend, for example going to home from work, or vice versa. When this happens, connectivity is fine (I can ping 8.8.8.8 for instance), but I cannot resolve names (eg. google.com). Restarting network-manager instantaneously fixes the issue.
