ntpd does not start, reliably.
What goes wrong? Is there an error message?
What I can find in journalctl -b:
systemd[1]: Dependency failed for Wait for ntpd to synchronize system
clock.
That is a failure of ntp-wait.service, not ntpd.service.
ntp-wait.service only serves a purpose (and only needs to be enabled) if
something is going to depend on it. For example, on my email servers, I
use a drop-in to configure dovecot.service to Requires= & After=
ntp-wait.service. This way, dovecot does not start until ntpd has set
the clock. This way, time never moves backwards, which Dovecot really hates.
If you're not actually using ntp-wait.service, just disable it:
sudo systemctl disable ntp-wait.service
This is before the network scripts I still use (no network-manager...).
network[2433]: WARN : [network] You are using 'network' service
provided by 'network-scripts', which are now deprecated.
network[2433]: WARN : [network] 'network-scripts' will be removed
from distribution in near future.
network[2433]: WARN : [network] It is advised to switch to
'NetworkManager' instead for network management.
Thus I think it fails due to lack of network connectivity.
If the above didn't answer your question, I'd check the following,
probably in this order:
1) Are you sure that the issue is that ntpd is not dealing well with the
network being up?
2) If so, can that be addressed with ntpd in some (trivial) fashion?
3) If not, try adding a drop-in (e.g.
/etc/systemd/system/ntpd.service.d/network.conf) that adds Wants= &
After=network-online.target. But note that your network subsystem must
actually support the network-online.target.
