I'll add my name to the list of people saying this is a blocker. I am currently working on a massive upgrade of 1000+ systems to Ubuntu 18.04 planned for early next year. Local dns resolution is an absolute must, and it must work out of the box. I can't update /etc/resolv.conf symlinks on thousands of systems manually. Even in an automated way, this is cumbersome and prone to break unexpectedly when updates get applied and revert the manual change. My DHCP server hands out a DNS server, and I expect my clients to ask that DNS server for all name resolution. How this long held tenant of network operation is being so horribly violated by systemd-resolved I don't understand. Did no one test this once? This is "Insanely broken and wrong".
Please fix this bug ASAP. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1624320 Title: systemd-resolved appends 127.0.0.53 to resolv.conf alongside existing entries Status in systemd package in Ubuntu: Confirmed Bug description: 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 active.
