Trying to reproduce this error:
I did:
$ lxc launch ubuntu-daily:artful
$ lxc exec relaxed-fly bash
Edited /run/systemd/network/10-netplan-eth0.network to become:
[Match]
Name=eth0
[Network]
DHCP=ipv4
DNS=fe80::307e:12ff:fec4:90ba
[DHCP]
UseMTU=true
RouteMetric=100
UseDNS=no
where fe80... address is the right address for the lxd host provided
dnsmasq.
Then I restarted everything:
$ sudo systemctl restart systemd-networkd systemd-resolved
$ systemd-resolve --flush-caches
$ ip link set dev eth0 down
$ ip link set dev eth0 up
# systemd-resolve --status eth0
Link 28 (eth0)

Looks like a correct and valid responses to me.
This is with 234-2ubuntu12.1
Seems like it works correctly. I do wonder, if the bug here is that
systemd-resolved is not up yet, and is not responding on dbus and/or
over 127.0.0.53 at the point in time? I.e.
https://bugs.launchpad.net/ubuntu/artful/+source/systemd/+bug/1734167
which is currently awaiting verification.
I'll try to revert the docker.io upload you did locally; and rerun all
of these tests again; to see if i can make this work again.
