I have a new Ubuntu 18.04 VM running in VirtualBox on Windows 10. I'm connected to a local network and able to resolve local addresses from Windows. However, my Ubuntu VM can only reach internet addresses.

From the command line, I see my DNS server listed as yet NetworkManager correctly displays the 10.x.x.x address of the DNS server on my local network.

I've fiddled around a bit with various network settings but I'm not sure how to resolve this. Any help is appreciated, thanks!

EDIT1: Interestingly, my DNS servers appear to be correct but my browser and shell commands like nslookup aren't using it by default. When I run nslookup , it works perfectly fine.

EDIT2: I tried the --natdnshostresolver1 command which @Fabby recommended, no luck there.

EDIT3: this is what my resolv.conf file looks like:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by 
# is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

  • What does VBoxManage modifyvm szVMName --natdnshostresolver1 on do where szVMName is tour Virtual Machine name? – Fabby May 25 '18 at 20:28
  • No difference, I've tried that too. – matthewcummings516 May 25 '18 at 20:35
  • How about $ systemctl status systemd-resolved. resolved is the 18.04 name resolver – Stephen Boston May 26 '18 at 0:53
  • @StephenBoston that command show this: Using degraded feature set (UDP) for DNS server – matthewcummings516 May 26 '18 at 1:20
  • Which isn't the correct DNS server. – matthewcummings516 May 26 '18 at 1:22

You can resolve this by installing the resolvconf app from the repository. Up until Ubuntu 18.04 LTS the app was installed by default.

$ sudo install resolvconf

After installing resolvconf on your VM client, add your desired DNS server to the /etc/resolvconf/resolv.conf.d/head file.

Place nameserver [your preferred dns server] at the bottom of the file. After rebooting your VM client, you will see the content of the /etc/resolvconf/resolv.conf.d/head file in your /etc/resolv.conf file, which will take precedence of other settings.

  • L.D James, that worked. . . I'd love to know what was wrong but either way, it's working now. Thanks! – matthewcummings516 May 26 '18 at 2:02
