The link target, stub-resolv.conf is the correct file for enabling systemd-resolvd. Various problems with the systemd-resolvd may be fixed by installing the libnss-resolve package (bug 1769016). Blank local domain problems have their own bug, 1699660 (fix is to use ~.). This report probably should be marked "invalid".

After much research and digging, it was discovered that the cause was the incorrect symbolic link /etc/resolv.conf file. The default install caused systemd-resolve to configure the link to point to the stub file: /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf Reomving that link and pointing it to the correct file solved the DNS lookup issue. The correct link looks like this: /etc/resolv.conf -> /run/systemd/resolve/resolv.conf Steps used to test the bug before fixing the link is to perform an nslookup on a local (non FQDN) machine that is in your local DNS (my router is my DNS server for this case) Here is an example of the incorrect output: $ nslookup web1 Server: 127.0.0.53 Address: 127.0.0.53#53 ** server can't find web1: SERVFAIL Switching the symbolic link solves the problem. Here is my solution: $ sudo rm -f /etc/resolv.conf $ sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf After switching the symbolic link, the nslookup functions properly. $ nslookup web1 Server: 192.168.1.1 Address: 192.168.1.1#53 Name: web1 Address: 192.168.1.107 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: systemd 237-3ubuntu10 ProcVersionSignature: Ubuntu 4.15.0-22.24-generic 4.15.17 Uname: Linux 4.15.0-22-generic x86_64 ApportVersion: 2.20.9-0ubuntu7 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Fri Jun 1 05:28:41 2018 InstallationDate: Installed on 2018-01-20 (131 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Release amd64 (20180105.1) MachineType: Dell Inc.
