Mon Mar 18 11:44:02 2024 - libs NOT ok

 Kernel image /boot/vmlinuz-4.4.0-210-generic unreadable. Can't check kernel version!
See comment #3 on https://bugs.launchpad.net/bugs/759725 for details and a permanent workaround.

 sudo seems to be installed, but an older version without support for files in /etc/sudoers.d/.

Please add the contents of /etc/sudoers.d/xymon to /etc/sudoers
and create /etc/sudoers.d/README to disable this warning:

  cat /etc/sudoers.d/xymon >> /etc/sudoers
  echo See /usr/lib/xymon/client/ext/libs >> /etc/sudoers.d/README
