Problem with timedatectl and network time synchronisation in 16.04
I have a dual-boot machine with Windows and Xubuntu 16.04. Because of Windows, the hardware clock is set to local time, so I had to use timedatectl to make Xubuntu aware of that after the upgrade to 16.04. The problem is that either I am not able to enable network time synchronization, or timedatectl is giving me wrong output.
systemctl list-units | grep time seems to indicate that the network time service is running:
systemd-timesyncd.service
loaded active running Network Time Synchronization
time-sync.target
loaded active active System Time Synchronized
At the same time, timedatectl returns this:
Network time on: yes
NTP synchronized: no
RTC in local TZ: no
Despite what the documentation says, sudo timedatectl set-ntp true has no effect. Any ideas?

Not sure if this is a bug with 16.04. I had the same problem and simply installing ntp helped.
sudo apt install ntp
After a reboot timedatectl showed ntp sync enabled.

It seems to be a conflict with ntpdate being on the machine as well. If you ONLY install ntp but not ntpdate, then ntp is allowed to work. With both on the machine, ntp won't stay up on next reboot.
Seems related to this bug.
