Tais - you should not have both services running. For you the solution should be:
$ systemctl disable --now systemd-networkd.service This will also disable associated units, including systemd-networkd- wait-online.service. ** Description changed: + [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 supported 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.
