If you want to switch to the new default configuration you can do this:

$ sudo ln -fs ../run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

And reboot. both ifupdown and network-manager, in 17.10 feed
nameservers to resolved and this is what default configuration should
look like.

Otherwise you need to specify nameserver in either /etc/resolv.conf
direct, or by supplying them to network-manager and asking it to
manage the /etc/resolv.conf.

Bug description:
  in the current daily 21 Aug 2017, I can ping 8.8.8.8 from a live
  session / installed session - running on virtualbox 5.1.26.

  However I cannot ping google.com - "Name or service not known"

  Kind of difficult to run ubuntu-bug here without a fully functioning
  network.

  Happy to provide more details - please can someone guide me producing
  a much better bug-report?

  ----

  my zesty VM is working just fine.  As of a week ago, my artful daily
  was working just fine also.

  ----

  
  * /etc/resolv.conf is empty file on most images built, which is not right, it should point to ../run/systemd/resolve/stub-resolv.conf. Should be fixed in image generation? systemd?

  * Adding a hack, to create /etc/resolv.conf if it does not exist, or
  is empty. src:systemd

  * network-manager does not consider that dns is managed by resolved if
  .53 is present in /etc/resolv.conf or if it points to stub-
  resolv.conf. src:network-manager

  * netcfg has integrtation w.r.t. /etc/resolv.conf and resolvconf.
  Needs checking / fixing

  * caster has resolvconf integration

  * livecd-rootfs has resolvconf integration
