I was trying out this exercise from the following IoT course. But when I tried to type in this: sudo systemctl status iotedge

I got this error message instead: Unit iotedge.service could not be found.

How do I resolve this?

Hi @alvin loke Greetings! Upon further investigation, we identified that the command sudo systemctl status iotedge is outdated and is taken from old versions of IoT Edge. I have tested the command on a VM where I deployed IoT Edge version 1.1.x and the command returns the output as shown in the tutorial. Please find the below image for reference.

However, the same command returns ***Unit iotedge.service could not be found. ***message when tested against IoT Edge version 1.4.x. To check the system status on 1.4.x versions, please use the following command sudo iotedge system status

Please refer the following image taken from Edge device with 1.4.9 version.

We will work on modifying the contents in the tutorial to be compatible with latest versions. Please refer the official documentation on IoT Edge 1.4 version which provides the same quick start guide here - https://learn.microsoft.com/en-us/azure/iot-edge/quickstart-linux?view=iotedge-1.4

Please let us know if you still have any questions and we would be glad to help you.
