TPM smoketest vyos 1.5 / current

Hi, I’m hoping someone might be able to share any experience or confirm the correct or best way to get TPM smoke tests working?

My pipeline Raid1 Smoke tests are passing, and I am building functional 1.5 rolling ISOs. An exception has been the TPM smoke tests, and I’ve not been able to successful work through the issue be it with an Ubuntu 20.04 agent or a Debian 12 agent.

Current error:

There should be this path

from vyos.utils.process import rc_cmd

The bug report T6298


Also does the docker when running smoketests have a virtual TPM defined so the TPM can be tested?

Or would this need the ISO to be loaded on baremetal to complete the smoketest?
