Thanks for the feedback! So it seems to be a race condition between a systemd "daemon-reload" (triggering the Netplan generator) and starting of NetworkManager.
We have a (partial?) reproducer in comment #11, but it's still unclear to me how the 12/24 h warm-reboot tests are being triggered. We have a workaround in comment #9. I think the core issue is that the Netplan generator should not re-write the NM configuration during daemon-reload and there's some pending work upstream of refactoring the Netplan generator accordingly: https://github.com/canonical/netplan/pull/552 ** Changed in: netplan.io (Ubuntu) Status: Incomplete => Triaged ** Changed in: netplan.io (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/2083129 Title: [Lenovo Ubuntu 22.04.4 Bug] netplan static IP address assignment use NetworkManager as renderer would be lost static ip Status in netplan.io package in Ubuntu: Triaged Status in network-manager package in Ubuntu: Invalid Status in netplan.io source package in Jammy: New Status in network-manager source package in Jammy: Invalid Bug description: On Ubuntu 22.04.4, to configure a system to use static address assignment, create a netplan configuration in the file, like /etc/netplan/00-installer-config.yaml. After assigning the network configuration abstraction renderer to NetworkManager not networkd in /etc/netplan/00-installer-config.yaml, then we do warm reboot test, some of the NIC interface lost their static ip in some reboot cycles when the rendered is NetworkManager, but networkd as a renderer is works well, all NIC interfaces can get their corresponding IP that configured in netplan confile file.
