nameserver 127.0.0.53

Can be worked around by directly adding a nameserver entry to /etc/resolv.conf
ubuntu@s5lp7:/var/log/installer$ cat /etc/resolv.conf
# This file is managed by man:systemd-resolved(8). Do not edit.
#
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.
nameserver 10.245.208.1
#nameserver 127.0.0.53
