I reproduced this with:
o. 10GB network card - Connected to network but with no DHCP on the network. This is a card I normally hard wire to direct connect to my NAS
o. 1GB network card - Connected to a network with DHCP
First attempt failed with this error.
On the second attempt, I disconnected the 10GB network card and reinstalled. / was reformatted. /boot was an existing boot and was not reformatted. The second attempt worked.
