We notice this here as well, as we're increasingly turning up new services and VMs without IPv4. It fails with a rather cryptic error message:
Jul 8 07:10:03 rpki-validator ntpdate[689]: Can't find host ntp.ubuntu.com: Name or service not known (-2) Jul 8 07:10:03 rpki-validator ntpdate[689]: no servers can be used, exiting Jul 8 07:10:03 rpki-validator ntpdate[726]: Can't find host ntp.ubuntu.com: Name or service not known (-2) Jul 8 07:10:03 rpki-validator ntpdate[726]: no servers can be used, exiting If the Ubuntu sysadmin team does not manage to dual-stack their public NTP service in three years, perhaps it is time for the ntpdate package to switch to 2.pool.ntp.org?
