How do I flush DNS cache in Ubuntu 22.04 LTS?

  • 772

I've already tried sudo systemd-resolve --flush-caches but it ends up showing sudo: systemd-resolve: command not found. So, how do I flush the DNS cache in Ubuntu 22?

    22.04 no longer comes with systemd-resolv and it is not installable by any packages that I can see in the default repos. An apt-cache search systemd-resolve shows that it is in the resolvconf-admin package, but when I tried installing that package it did not install systemd-resolve.

    22.04 comes with resolvectl instead.

    You can use the following command to flush your caches:

    sudo resolvectl flush-caches

    Hope this helps!
