While running the test plan, I discovered an issue with the way the systemd service is configured. The service file configures Before=network-pre.target but doesn't set DefaultDependencies=no. On Noble and Jammy, this causes a dependency cycle to occur:
Sep 03 16:27:16 ubuntu systemd[1]: sysinit.target: Found ordering cycle on cloud-init.service/start Sep 03 16:27:16 ubuntu systemd[1]: sysinit.target: Found dependency on systemd-networkd-wait-online.service/start Sep 03 16:27:16 ubuntu systemd[1]: sysinit.target: Found dependency on systemd-networkd.service/start Sep 03 16:27:16 ubuntu systemd[1]: sysinit.target: Found dependency on network-pre.target/start Sep 03 16:27:16 ubuntu systemd[1]: sysinit.target: Found dependency on azure-proxy-agent.service/start Sep 03 16:27:16 ubuntu systemd[1]: sysinit.target: Found dependency on basic.target/start Sep 03 16:27:16 ubuntu systemd[1]: sysinit.target: Found dependency on sysinit.target/start Sep 03 16:27:16 ubuntu systemd[1]: sysinit.target: Job cloud-init.service/start deleted to break ordering cycle starting with sysinit.target/start From 25.04, cloud-init doesn't depends anymore on systemd-networkd-wait- online.service which mitigate the issue. However, I think similar cycle could still happen with other services. The cycle involving cloud-init on 22.04 and 24.04 completely breaks the image if the agent is pre-installed as it prevents cloud-init from running. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2115197 Title: [SRU] Backport azure-proxy-agent 1.0.30-0ubuntu3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/azure-proxy-agent/+bug/2115197/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
