This is bug is blocking any experiments with AWS prefixes because DHCP stops working when such prefixes are assigned to the interface.
** Patch added: "Cherry-pick from upstream" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1945888/+attachment/5535501/+files/sd-dhcp6-client.patch -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1945888 Title: DHCPv6 too strict when the response is missing IAID for some sections Status in systemd package in Ubuntu: Confirmed Bug description: Systemd incorrectly ignores whole messages when IAID is missing for some sections. This has been reported upstream [1] and fixed [2]. $ lsb_release -rd Description: Ubuntu 21.04 Release: 21.04 $ apt-cache policy systemd systemd: Installed: 247.3-3ubuntu3.6 Candidate: 247.3-3ubuntu3.6 Version table: *** 247.3-3ubuntu3.6 500 500 http://no.archive.ubuntu.com/ubuntu hirsute-updates/main amd64 Packages 100 /var/lib/dpkg/status 247.3-3ubuntu3.4 500 500 http://security.ubuntu.com/ubuntu hirsute-security/main amd64 Packages 247.3-3ubuntu3 500 500 http://no.archive.ubuntu.com/ubuntu hirsute/main amd64 Packages What is expected to happen is that systemd will ignore only the relevant part of the message, not the entire message. What is happening is that the entire message is ignored, leading to DHCP leases not being renewed. This is fairly easy to replicate e.g in AWS by enabling both an IPv6 prefix and an IPv6 single address to the same interface.
