Percept getting TPM error after yum upgrade

Question

Are we not expected to run 'yum upgrade' on the Percept devices?

Recently I ssh into the device and it mentioned there were updates from the Mariner package repository. Wanting to stay secure, I ran 'sudo yum update' to update.

After they updated, edgeAgent is getting the TPM/HSM errors below.

My process:

update to Azure-Percept-DK-1.0.20210929.1747-public_preview_1.0

connect to http://10.1.1.1 and configure to IoT Hub using DPS

verify it works via portal and goto http://(IPADDRESS):3000/

root [ /var/custom-configs/home/ksaye ]# iotedge --version
iotedge 1.1.0

update with latest Mariner (dated 11/16/2021)

yum check-update
yum upgrade

check new version of IoT Edge

root [ /var/custom-configs/home/ksaye ]# iotedge --version
iotedge 1.1.1

reboot

reboot now

ssh back in and get the error from edgeAgent:

Accepted Answer

For others, there appears to be an issue with the current updates which will be fixed in the near future. For now, flash back to the factory firmware. :)
