Public bug reported:
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.
