    Are you sure you are using Ubuntu 16.04? Please update your post with output of cat /etc/os-release and ls -al $(which init). – N0rbert Dec 21 '17 at 17:08

  1. First you need to check if systemd package is installed - sudo dpkg -l | grep systemd.
  2. If not then install it by hands sudo apt-get install systemd. But if it does it might be damaged, so you may try to reinstall it sudo apt-get install --reinstall systemd.
  3. If the package is installed, even after reinstallation it does not work, list the full path of the files inside this package sudo dpkg -L systemd. Maybe binary files are located in a directory that is not included into $PATH variable.

    What is the output of sudo apt-cache search systemd? – M. Dm. Dec 21 '17 at 10:31
  • This is output of sudo apt-cache search systemd "live-config-systemd - Debian Live - System Configuration Scripts (systemd backend) nagios-plugins-contrib - Plugins for nagios compatible monitoring systems" – Vignesh Ramamoorthy Dec 21 '17 at 10:52

    Did you run sudo apt-get update after the system was installed? I think you have some problem with your repositories. – M. Dm. Dec 22 '17 at 09:41

    Please fix your Answer: apt-get install --reinstall systemd – Marco Dec 12 '18 at 21:30
  • Just reinstall the package apt-get install --reinstall systemd and see if any of the paths from dpkg -L systemd is in you echo $PATH. – pegasuspect Aug 26 '20 at 17:30
  • If you are using docker, you might want to add apt-get install systemd command to the dockerfile, and rerun the docker. This solved the issue for me – Nir Sep 26 '25 at 08:26
