Comment #21 fixed the issue for me. Bug does also apply to current 12.10 release (upgrade: 16/11/2012).

I recently upgraded to Ubuntu 12.10 Beta 1 from a more-or-less stock installation of Ubuntu 12.04 (it had only been installed for about 3-4 hours before the upgrade). This means that I am now using network- manager 0.9.6.0-0ubuntu7. On startup, network-manager connects to my router without any issues, but I am then unable to resolve any domain names (beyond localhost); I can't browse to any websites, ping any servers using their domain names, etc. There were no problems doing any of this while using 12.04, and I did not do anything other than perform the upgrade to 12.10 Beta 1 before this happened, so what I was expecting to happen was that I would continue to be able to use DNS as usual. On poking around a bit, I discovered that dnsmasq is running as it should be (listening on 127.0.1.1) but that the config file that it is trying to use, /var/run/nm-dns-dnsmasq.conf, is completely empty. This appears to be the source ofthe problem, as I can fix the issue by doing the following: 1) Kill the /usr/sbin/dnsmasq process that is automatically started (by network-manager?). 2) Manually create /var/run/nm-dns-dnsmasq.conf and add lines such as the following (this line identifies an OpenDNS server): server=208.67.222.222 3) Manually start the /usr/sbin/dnsmasq using exactly the same options that were passed to it when it was started automatically. So, I'm guessing this file should be non-empty. (Another workaround, by the way, is to manually create an /etc/resolv.conf file with appropriate nameserver lines and then restart the networking service, but AFAIK that solution simply bypasses dnsmasq entirely.)
