After a completely fresh install (on a new SD card), I'm hitting the same error, but now just this:
Job for resilio-sync.service failed. See 'systemctl status resilio-sync.service' and 'journalctl -xn' for details
systemctl status resilio-sync.service gives the following:
resilio-sync.service - Resilio Sync service
Loaded: loaded (/lib/systemd/system/resilio-sync.service; enabled)
Active: failed (Result: start-limit) since Sat 2017-05-20 12:52:49 UTC; 41min ago

I am following the instructions here to the letter.
