Time in Ubuntu 16.04 not updating from internet

Ubuntu 16.04 works with timedatectl / timesyncd

Check the timseyncd service is ok: systemctl status systemd-timesyncd

Possibly something is blocking the service (eg: ntpd installed), so it avoids syncing to avoid conflicts.

Another possibility is that you may be running a VirtualBox and you may see an error like:

● systemd-timesyncd.service - Network Time Synchronization
   Loaded: loaded (/lib/systemd/system/systemd-timesyncd.service; enabled; vendor preset: enabled)
  Drop-In: /lib/systemd/system/systemd-timesyncd.service.d
           └─disable-with-time-daemon.conf
   Active: inactive (dead)
Condition: start condition failed at Mon 2018-02-12 17:40:50 AEDT; 1min 31s ago
           ConditionFileIsExecutable=!/usr/sbin/VBoxService was not met
     Docs: man:systemd-timesyncd.service(8)

This was a solution for this case: sudo VBoxService --timesync-set-start. Inspired from this issue with a similar error


In my case what I did is comment the line ConditionFileIsExecutable=!/usr/sbin/VBoxService in file /lib/systemd/system/systemd-timesyncd.service.d/disable-with-time-daemon.conf and then:

sudo systemctl daemon-reload
sudo systemctl start systemd-timesyncd

All started to work again.
