I had a similar issue but not quite the same. I upgraded from Precise (installed at the factory on a Dell Sputnik device) to Trusty. After upgrade, DNS did not work. I did have the /etc/resolv.conf symlink, but the content generated by resolvconf just listed 127.0.0.1 twice (the old address). Following the suggestion at http://askubuntu.com/a/462377/75121, I purged and reinstalled resolvconf --which didn't immediately fix it--and then rebooted. After reboot, the resolv.conf now lists the correct address of 127.0.1.1 followed by the old address of 127.0.0.1, and DNS resolution works.
