I assume you're setting up 20.04 server? I just (from my installation
and configuration notes) did this:-

See 
https://www.tecmint.com/configure-network-static-ip-address-in-ubuntu/
Set up networking:-
Edit /etc/netplan/???? to look like this:-

# This is the network config written by 'subiquity'
network:
  ethernets:
    enp2s0:
      addresses:
      - 192.168.2.x/24
      gateway4: 192.168.2.1
      nameservers:
        addresses:
        - 208.67.222.222
        - 208.67.220.220
        - 192.168.2.1
        - 8.8.8.8
        - 8.8.4.4
  version: 2


Then do
sudo netplan apply

This is from my personal notes. Your Ethernet port name may be
different. Don't change it.

Hope that gets you going.
