Hey Steve :)

So, this system is quite old. I think the first install was 16.04 and it
went through a bunch of upgrades (mostly interim until 20.04 and then to
22.04). It would not surprise me if things weren't pristine. I'll give
some info and you can tell me what else to provide:

$ cat /etc/netplan/01-network-manager-all.yaml 
# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

$ sudo netplan get all
network:
  version: 2
  renderer: NetworkManager

$ ls /etc/systemd/network
$

$ cat /etc/systemd/networkd.conf
#  This file is part of systemd.
...
# See networkd.conf(5) for details.

I don't recall enabling systemd-networkd, but a lot has happened over
the last 7 years, 4.5 of those while developing Ubuntu. :)
