I have this same issue on a clean install of xubuntu 17.10. My biggest issue is that it seems to return after reboot (has reoccurred twice now, i assume after applying updates or something as I have restarted more than twice). I have previously been doing the following to fix:
sudo rm /etc/resolv.conf
sudo ln -s /run/resolvconf/resolv.conf /etc/resolv.conf
systemctl restart resolvconf
I have a backup of the original resolv.conf (mv resolv.conf resolv.conf.old).
