    Hi,

     

    Can this be updated for Plesk Obsidian, Ubuntu 18?

    service named-chroot restart
    Failed to restart named-chroot.service: Unit named-chroot.service not found.

    service named-chroot status
    Unit named-chroot.service could not be found.

    Please check step 6:

    Restart BIND service (named-chroot for CentOS, bind9 is Ubuntu/Debian):

    So for Ubuntu it should be # service bind9 restart

    You shouldn't manually update your resolv.conf, because all changes will be overwritten by data that your local DHCP server provides. Link to a correct tutorial: https://talk.plesk.com/threads/how-to-enable-dns-caching-for-plesk-email-security.357504/

    In some cases, resolv.conf is not being overwritten by any other services. However, thank you for the link, I am sure that it will be helpful for other users!
