    I could resolve this.

    The network manager was the culprit.

    I got answer from a thread at https://forums.centos.org/viewtopic.php?t=8660

    what is your output when you run

    cat /etc/resolv.conf

    just seeing if you get something different than what you posted

    I am running Ubuntu 20.04.1 LTS and was getting the error:

    dig: parse of /etc/resolv.conf failed

    when I ran a Dig or nslookup.

    dig example.com

    The old /etc/resolv.conf config was still in place, which causes a conflict between the resolvconf and systemd-resolved services.

    In my case /etc/resolv.conf was a symbolic link pointing to /run/resolvconf/resolv.conf (the old config).

    The following commands fixed it:

    sudo rm /etc/resolv.conf
sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
sudo systemctl restart resolvconf

    Grant’s solution of changing the symbolic link worked for me.

    I’m running Ubuntu 20.04.3 LTS Desktop. When executing:

    host linuxfoundation.org

    I was getting the error message:

    host: parse of /etc/resolv.conf failed

    After executing the commands listed in Grant’s answer, I am now getting the same results as in the Linux Foundation’s Intro to Linux Course on edx.org.

    I would’ve upvoted Grant’s answer but I don’t have enough points.
