I confirm that I have the same issue since upgrading today to the stable version Ubuntu Quantal. Manual creation of a correct resolv.conf file fixes the problem temporarily. But as soon as I connect to a different network, this operation needs to be repeated. This seems a very serious bug, it needs high priority. I don't know how to debug it. I had dnsmasq installed prior to upgrading. Could this be related in any way?
