Turns out dropping "debian/patches/units-Don-t-start-systemd-udev-
trigger.service-in-a-conta.patch" (that we want to drop anyway) makes a
difference here, i.e. removing the "ConditionVirtualization=!container"
line from /usr/lib/systemd/service/systemd-udev-trigger.service.
# apt install systemd udev # upgrade systemd & udev to v249
# systemctl restart systemd-udev-trigger # run the 'udevadm trigger' commands
# systemctl restart systemd-networkd # restart networkd to re-run the DHCPv4
client.
That is even though the systemd-udev-trigger.service fails to execute
successfully:
# systemctl status systemd-udev-trigger.service

Title:
DHCPv4 (IAID+DUID) networking broken in LXC containers
Status in lxd package in Ubuntu:
New
Status in systemd package in Ubuntu:
New
Bug description:
DHCPv4 networking does not work in the default IAID+DUID
(ClientIdentifier=duid) mode in LXC containers, using systemd-networkd
v249.5-2ubuntu1. Static configuration and DHCPv6 work without problem.
Reproducer:
$ lxc launch ubuntu-daily:jammy jj
$ lxc exec jj bash
# add-apt-repository ppa:ci-train-ppa-service/4704
# apt install systemd # install systemd 249.5-2ubuntu1
# cat /etc/systemd/network/00-test.network
[Match]
Name=eth0
[Network]
DHCP=ipv4
# systemctl restart systemd-networkd.service
# networkctl
IDX LINK TYPE OPERATIONAL SETUP
[...]
611 eth0 ether carrier failed
A workaround is to avoid IAID+DUID mode via:
[DHCPv4]
#ClientIdentifier=mac
ClientIdentifier=duid-only
Interesting logs:
