I can't reproduce this issue. Can you explain what I'm missing?
$ grep nameserver /etc/resolv.conf
# run "systemd-resolve --status" to see details about the actual nameservers.
nameserver 127.0.0.53
$ lxc launch ubuntu-daily:bionic

Container name is: frank-jaguar

So can you elaborate where you're seeing this problem?

Title:
systemd-resolve default nameserver 127.0.0.53 disables resolution in
guest systems
Status in systemd package in Ubuntu:
Incomplete
Bug description:
When the default nameserver, which is set by systemd-resolve, is
127.0.0.53, guest systems (libvirtd, lxc, snaps, anbox, etc) won't
work unless there's a non 127.0.0.x nameserver (eg. 8.8.8.8) in
/etc/resolv.conf. Because the dnsmasq in these guest machines try to
resolve to 127.0.0.53 and can't find the real nameserver.
The quick fix is of course to:
sudo rm /etc/resolv.conf
sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
But that's not the default.
