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.

[Impact]
When all interfaces "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.

This will disable systemd-networkd and associated units, including systemd-networkd-wait-online.service. NetworkManager and systemd-networkd should not be running at the same time. On desktop, NetworkManager is the default network stack.
[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.
https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1982218/comments/21 also mentioned the problem on Lunar. |
[NOTE]
If you are running a desktop system and you see this issue, you should run:
$ systemctl disable --now systemd-networkd.service
This will disable systemd-networkd and associated units, including systemd-networkd-wait-online.service. NetworkManager and systemd-networkd should not be running at the same time. On desktop, NetworkManager is the default network stack.
