I have setup an Ubuntu server with a static IP and I cannot get the DNS to work. Pinging any domain (such as google.com) will not redirect me. I have tried editing /etc/resolv.conf, but that didn't work and it just keeps getting overwritten.

I also tried adding the dns-nameservers x.x.x.x x.x.x.x line to /etc/network/interfaces. I tried this using both my ISP's DNS (obtained it from my Windows desktop with ipconfig) and Google's (, but it still won't work.

A work around to solve this is to temporarily add the domains you need to the /etc/hosts file.

That provided enough connectivity to sudo aptitude to resolve the broken dependencies on the system.

After the upgrade, Ubuntu rebooted normally and I could remove the static IPs from the hosts file again.

I used the following to capture the domains I needed to update and put them into a text file: sudo apt-get update >> domains.txt

I used the following to grab the IPs I needed:

sh domain-nslookup.sh >> apt-domains.txt

The following is the sh file I created and saved as domain-nslookup.sh:

for DOM in `cat ./apt-domains.txt`;
    nslookup $DOM |gawk -F": " '/Address/{print $2}'
    printf "\t%-4s" $DOM
printf "\n"

After verifying that it worked as planned, I added the IPs and domains to the hosts file:

sudo sh domain-nslookup.sh >> hosts

    example would not hurt, isn't it?

  • The script didn't quite work for me, but this is a good reminder that while I'm solving my DNS problem, setting up /etc/hosts with what apt wants makes things a lot easier. Thanks! Commented Jun 25, 2020 at 1:44

before anything test that you can actually resolve without configuration setup.

Try the following:


if that works make sure that your resolv.conf file contains the following:


It might be that NetworkManager is running also, and that overrides manual changes

  • So this just worked perfectly, thank you very much. Any chance you can explain why this worked, but when I put the following in resolv.conf it failed? nameserver nameserver Commented Nov 20, 2014 at 19:00
  • can you paste the content of your resolv.conf? Commented Nov 20, 2014 at 19:45
  • According to the man page, the preferred format is: dns-nameservers

  • I like the command getent hosts www.google.com. The command getent uses the systems way of looking up names. nslookup or ` dig` uses only the DNS system. Also look up the manual page for resolvconf. That is what is using the dns-nameserves directive in /e/n/interfaces and other DNS sources to manipulate /e/resolve.conf. So if the package resolveconf is installed, never change the contents of /e/resolv.conf manually. Use the command.

    careful! replacing the content of /etc/resolv.conf (which is a symlink actually) will break the package resolvconv. So don't recommend that without further inquirements.
