security.ubuntu.com has no IPv6 support

security.ubuntu.com and most archive.ubuntu.com has no IPv6 support and ipv6.security.ubuntu.com does not exist, so you can't install security fixes to ubuntu systems which does only have an IPv6 connection.

Steps to reproduce:
1.) Check that you have IPv6:
$ ping6 ipv6.google.com
PING ipv6.google.com(fx-in-x68.1e100.net) 56 data bytes
64 bytes from fx-in-x68.1e100.net: icmp_seq=1 ttl=57 time=9.87 ms
64 bytes from fx-in-x68.1e100.net: icmp_seq=2 ttl=57 time=10.2 ms
^C
--- ipv6.google.com ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 9.876/10.067/10.259/0.216 ms

2.) Test IPv6 support on security.ubuntu.com:
$ ping6 security.ubuntu.com
unknown host

$ ping6 ipv6.security.ubuntu.com
unknown host

The Ubuntu repo and the Ubuntu security repo especially should have IPv6 support.
Ubuntu does support ipv6 (https://wiki.ubuntu.com/IPv6) and is involved with it.

Debian has IPv6 already on their repos btw.:

$ ping6 security.debian.org
PING security.debian.org(wieck.debian.org) 56 data bytes
64 bytes from wieck.debian.org: icmp_seq=1 ttl=56 time=29.1 ms
64 bytes from wieck.debian.org: icmp_seq=2 ttl=56 time=30.1 ms

Thank you for helping with making Ubuntu better by reporting this bug.
The issue was reported earlier against update-manager by bug #241305. However, because it is not a bug in update-manager, but more a feature request, the bug has been marked as Invalid and an entry was created in the Request Tracker with the number #2485, which is located at <https://rt.ubuntu.com/>.
However, it is unlikely that IPv6 support will be introduced any time soon.

I'm marking this bug as a duplicate of bug #241305 still to make sure you can follow any possible future discussion over there and to keep our bugs collection nice and clean.
