Configuring a static IP address generates a netplan file without a gateway

[Tony Espy]

Configuring a static IP address for an ethernet device on an Ubuntu Core 16 system generates a netplan file without a gateway specified, thus the console-conf WaitDefaultRouteTask eventually times out. Here's the netplan file generated:

network:
  ethernets:
    eth0:
      addresses:
      - 10.155.114.58/21
    eth1:
      addresses: []
  version: 2

Steps to reproduce:

1. Run console conf
2. Select ethernet interface
3. Configure a static IP address

Subnet: 10.155.112.0/21
Address: 10.155.114.58
Gateway: 10.155.112.1

Expected Results:
System come online with specified static IP address and gateway.

Actual Results:
Console-conf time out error is displayed.

I understand this is also blocked on having the necessary support in netplan.

You can specify the gateway in netplan files, right next to "addresses:", with "gateway4:" and "gateway6:" (see man netplan). What's missing?

You're quite right, I was getting confused with https://bugs.launchpad.net/ubuntu/+source/subiquity/+bug/1626617 ("console-conf does not allow to set up dns for static ip") which is going to be the next problem in this thread one presumes (you can't create an account from the store without working dns...).
