I've installed chrony on my plucky system to give it an early test.
I've noticed in my system journal this message getting logged every 2
seconds:
Could not connect to [2620:2d:4002:1::3123]:4460 (4.ntp.ubuntu.com)
Indeed I do not have an ipv6, so that makes sense. However it's unclear
whether chrony is then falling back to ipv4 or if it's getting blocked
on failing to use ipv6.
`resolvectl query 4.ntp.ubuntu.com` shows:
4.ntp.ubuntu.com: 2620:2d:4002:1::3123 -- link: wlp1s0
91.189.91.113 -- link: wlp1s0

Bug description:
Ubuntu shall be secure by default, therefore utilize Network Time
Security (NTS), as time is the trust anchor for many cryptography
related processes (e.g. certificates).
NTS was previously enabled in chrony (LP: #2084585) and comes pre-
installed in certain Ubuntu cloud images. Still, in Ubuntu
Desktop/Server and other generic Ubuntu images we rely on systemd-
timesyncd (without support for NTS [1]). This leads to a situation
where we have to maintain two time-daemons in "main", while still not
using NTS on most systems.
