Public bug reported:
systemd-resolved, or more precisely the hook script /lib/systemd/system
/systemd-resolved.service.d/resolvconf.conf, causes resolvconf to add
127.0.0.53 to the set of nameservers in /etc/resolv.conf alongside the
other nameservers. That makes no sense because systemd-resolved sets up
127.0.0.53 as a proxy for those other nameservers. The effect is
similar to bug 1624071 but for applications doing their own DNS lookups.
It breaks any DNSSEC validation that systemd-resolved tries to do;
applications will failover to the other nameservers, bypassing
validation failures. And it makes failing queries take twice as long.
/etc/resolv.conf should have only 127.0.0.53 when systemd-resolved is
