unauthorized: authentication required when using ACR

I am not able to run my C#-based IoT Edge Module on my Azure Ubuntu 18.04 VM because I see an InternalServiceError.

Expected Behavior

My C# IoT Edge Module should run on my Ubuntu VM

Current Behavior

When I run sudo journalctl -u iotedge I get this error message:

InternalServerError, content: Some(Object({"message": String("Get https://xyz.azurecr.io/v2/entrymodule/manifests/0.0.1-amd64: unauthorized: authentication required")})) })

Steps to Reproduce

1. Configure an Ubuntu 18.04 Azure VM as described here
2. Push an Azure IoT C# Module to the device using Visual Studio Code or Visual Studio 2017 as described here to ACR
3. Deploy the module to the Edge device

Can we close this issue if the tutorials have been updated?

Just to make sure, have you added your ACR credentials via the portal for your specific modules?

Specifically under Your Azure IoT Hub portal --> Click IoT Edge – > Choose your edge device --> Click Set modules. A screen comes up where you can add/edit your ACR credentials.
