When deploying custom-ubuntu.tar.gz, the machine stays with "Deploying" even after "Installation complete"

[kojiwell]

When I make and then deploy a custom-ubuntu.tar.gz to a baremetal machine on our MAAS, the machine somehow stays "Deploying" even after "Installation complete - Node disabled netboot" is logged in the Event log. The machine doesn't respond to ping. And 30 minutes later, the machine will be marked as "Failed deployment."

I checked the machine's status via a remote console; the OS was up; I could log in. However, the /etc/netplan/50-cloud-init.yaml doesn't exist, which is supposed to be generated during the deployment. So, there seems to be an issue on finalizing the deployment process after the installed OS is booted.

Here's the snippet of the Event log around the end of deployment.

Here's the bottom lines in the Installation output. Curtin seems to have finished installation without an issue.

Here's how I have registered the ubuntu-custom image.

git clone https://github.com/canonical/packer-maas
cd packer-maas/ubuntu
make custom-ubuntu.tar.gz
maas $MAAS_USER boot-resources create name='custom/ubuntu2204' title='custom/ubuntu2204' architecture='amd64/generic' filetype='tgz' base_image='ubuntu/jammy' content@=custom-ubuntu.tar.gz

Thank you for your attention. I will appreciate any comments.
