Just found that systemd thought networking.service was having trouble on my machine.
When I checked "journalctl -xe" I found the following: ifup[18149]: run-parts: /etc/network/if-pre-up.d/whereami exited with return code 1 ifup[18149]: ifup: pre-up script failed systemd[1]: networking.service: Main process exited, code=exited, status=1/FAILURE
