One needs to do a :
$ systemctl daemon-reload
After putting the file there.
The error is
/lib/systemd/system/ntp.service:6] Unknown lvalue '+ EnvironmentFile' in
section 'Service'
Removing the 'plus-sign' won't fix it.
[OT but important bread-crumbs for others...]
The systemd-timesyncd.service works out of the box - no need to do anything but enable it in systemd
- but if you need your own time server it fixes nothing. And if you want to use
systemd-timesyncd.service and point it at your own time server you need to edit
/etc/systemd/timesyncd.conf
- the keyword Servers needs a Capital 's' and the s at the end.
