2025-01-29T17:01:55Z INFO ImageProvision: VSphere: Image Provision is successful
Appliance configuration was prepared successfully
Starting the upgrade
Started upgrade, waiting for the operation to complete
(ImagePreflightCheckErrorOnPrem) Upgrade Operation Failed with error: "{\n "code": "ImagePreflightCheckError",\n "message": "preflight checks failed: ImageNotFound"\n }"
Code: ImagePreflightCheckErrorOnPrem
Message: Upgrade Operation Failed with error: "{\n "code": "ImagePreflightCheckError",\n "message": "preflight checks failed: ImageNotFound"\n }"
Any ideas about to debug and resolve this?
Thanks

- Run a Preflight Check Before Upgrade
az login az account set --subscription "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" az connectedmachine upgrade preflight-check --name <resource-bridge-name> --resource-group <resource-group> az connectedmachine show --name <resource-bridge-name> --resource-group <resource-group>Run the following command to check if Azure Arc Resource Bridge is properly deployed
az acr repository list --name <your-acr-name>If the image is missing, re-download it manually:
docker pull mcr.microsoft.com/arc/azurearcbuilder:<version>
Try Upgrade with Debug mode
az arcappliance upgrade <resource-bridge-name> --config-file <path-to-config-file> --debugCheck any logs reported and Check Logs for Detailed Errors
