Add some findings when I tried to reproduce this issue on vSphere, I believe dbus was not ready when cloud-init init-local/init services were still running.
* release-20240710 (netplan ver: 1.0-2ubuntu1.2) netplan apply finished with Exit Code 0, but logged Failed to connect to system bus: No such file or directory and Falling back to a hard restart of systemd-networkd.service. This means even dbus is not ready, netplan apply could finish correctly. * release-20250403 (netplan ver: 1.1.1-1~ubuntu24.04.1) netplan apply stuck. ** Changed in: netplan.io (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2109487 Title: netplan apply - cannot connect to system bus at boot time To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/2109487/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
