Ubuntu – configure Time Synchronisation on Ubuntu 16.04.4 but timedatectl give Failed to create bus connection: No such file or directory

16.04networkingntpservicestime

When I look at https://help.ubuntu.com/lts/serverguide/NTP.html I can see the current time configuration with timedatectl but I always get an error.

$ timedatectl status
Failed to create bus connection: No such file or directory
$ sudo timedatectl status
Failed to create bus connection: No such file or directory

# timedatectl status
Failed to create bus connection: No such file or directory

There are no ntp packages installed and the service is running normal.

I found the solution here: Thanks for the answer but I found the solution here: https://stackoverflow.com/questions/43907925/ubuntu-timedatectl-fails-in-docker-container

On a minimal Ubuntu 16.04 installation (like mine) the dbus package is not installed. So apt-get install dbus resolved the problem.
