Hello Jamie, or anyone else affected,

Accepted systemd into jammy-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/249.11-0ubuntu3.11 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  systemd wait-online now times out after jammy and lunar upgrade

Status in systemd package in Ubuntu:
  Invalid
Status in systemd source package in Jammy:
  Fix Committed
Status in systemd source package in Lunar:
  Fix Committed

Bug description:
  [Impact]

  When all interfaces are "not required for online", e.g. when they are
  marked "optional: true" in netplan, systemd-networkd-wait-online will
  timeout. Or, in other words, systemd-networkd-wait-online will timeout
  even though all interfaces are ignored, hence none of them will ever
  be marked as "ready." Depending on what units depend on network-
  online.target, this can delay boot by 120 seconds (the default timeout
  for systemd-networkd-wait-online).

  [Test Plan]

  1. Create a new LXD container. These instructions assume jammy is the
  release, but the same can be done for lunar.

  $ lxc launch ubuntu-daily:jammy jammy
  $ lxc exec jammy bash

  2. Once in the container, modify the default /etc/netplan/10-lxc.yaml
  so that eth0 is configured with "optional: true":

  $ vi /etc/netplan/10-lxc.yaml # Use whatever editor you like
  $ cat /etc/netplan/10-lxc.yaml
  network:
    version: 2
    ethernets:
      eth0:
        dhcp4: true
        dhcp-identifier: mac
        optional: true

  3. Re-generate and apply the netplan configuration.

  $ netplan generate
  $ netplan apply

  4. Manually run systemd-networkd-wait-online, and observe that all
  links are ignored, and the command times out:

  $ SYSTEMD_LOG_LEVEL=debug /lib/systemd/systemd-networkd-wait-online 
--timeout=10
  Found link lo(1)
  Found link eth0(19)
  lo: link is ignored
  eth0: link is ignored
  Timeout occurred while waiting for network connectivity.

  [Where problems could occur]

  This patch partially re-instates a patch remove in bug 1982218.
  However, instead of exiting if all links are unmanaged, we exit if all
  links are ignored in manager_configured(). If the patch was wrong, we
  may re-introduce bug 1982218, so as part of this SRU verification,
  that bug should be tested too. Any other regressions would also be
  related to systemd-networkd-wait-online behavior.

  [Original Description]

  On Ubuntu 22.04 desktop system using network-manager and upgrading to
  systemd 249.11-0ubuntu3.10, wait-online now times out which prevents
  logins (GDM, ssh, console) until it does time out. This seems to be
  introduced by the change for
  https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1982218.
