A user tries to install ONOS 1.6.0-snapshot (current master) on Ubuntu 16.04 (64 bit).
When trying to start ONOS (either while pushing the bits with onos-install, or manually using sudo service onos start), the following error is returned:
Warning: onos.service changed on disk. Run 'systemctl daemon-reload' to reload units
I suspect typing on the target machine 'sudo systemctl daemon-reload onos' and modifying accordingly onos-install would solve the issue.
