Comment 19 for bug 1477980

Works as designed. That is, if the default Ubuntu mirror is not reachable the user is prompted to configure the network.

> Default gateway 10.20.0.1 - is the host where Fuel VM resides.

This doesn't mean the Internet is reachable, DNS is working, etc.

Please redeploy the master node from the scratch, run the following commands while fuel
menu is active (i.e. choose 'Shell Login' in the menu, or login via ssh, etc)

host archive.ubuntu.com
tracepath archive.ubuntu.com

and post the output here.
