I'm unable to get an IP address assigned through DHCP during system boot.

I was unable to get either IPV4 or IPv6 working for my NIC enp5s0 (details below) during my vanilla, single disk install of Ubuntu 18.04 Server, so I proceeded without the Network. Unfortunately, I'm unable to configure it properly post installation.

My 01-netcfg.yaml file is below and I did remember to run:

sudo netplan generate
sudo netplan apply

I'm able to get an IP address with this command:

sudo dhclient -v enp5s0

so I updated the installation, but the problem persists. It must be a configuration problem but I can't figure out what it is. Troubleshooting pointers appreciated!

enp5s0
