Dear Maintainer,
With the current apparmor profile, the ntp daemon does not start. The log is:

I can confirm the apparmor denials, however I cannot reproduce startup
errors caused by this.

I have 2 systems where this happens, but I also confirm that this does
not happen on all systems (Debian testing) where ntp is installed. Any
suggestions on how to diagnose this?
Regards,
Nuno.
