Public bug reported: Hi This bug is a variant of https://bugs.launchpad.net/cloud-init/+bug/1997922.
I got this error only when PXE booting a target with a modem that has dual interface support, and using ubuntu-22.04.2-live-server-amd64.iso or ubuntu-22.04.1-live-server-amd64.iso. After a manual installation, the target boots fine without this error. Detected modems that cause this error: Quectel EG25 Quectel RM510Q-GLHA Sierra Wireless MC7455 Failure in cloud-init prevent automatic installation of targets in our production. Tested solution: After studying the info in bug 1997922, I downloaded https://github.com/canonical/cloud-init/blob/main/cloudinit/net/__init__.py and changed line 1043 to: if driver == "mscc_felix" or driver == "fsl_enetc" or driver == "qmi_wwan": Then created a customized version of ubuntu-22.04.2-live-server- amd64.iso and tested in our production line, and now everything works fine.
