Device keeps in progress state after IsInstalled succeeds about iot-hub-device-update HOT 4 CLOSED

Hi @Voxel07,

Thank you for your questions, please see our responses below-

1. For 1 above, you are correct the current flow for the download, install and apply phases is shown here.. Any reason you need to skip the apply action?
2. For 2 above, removing Files after the download action is a way of clearing the file list for the next deployment without consuming an additional IoT hub messages from your IoT Hub message quota. Today we have done this after download is complete, as you have observed. Is it a common scenario for your IoT device set up where you need to redownload the file after a reboot?

Thanks for the Answer.

1. No, there is no reason to skip the apply step. But say for example, that the agent is running and for some reason the same update gets deployed again. Then there is no check in place to stop a new installation. That's the case I wanted to catch, maybe that's implemented in swUpdate, I don't know.
2. It's not common or a planed workflow. I was just thinking of scenarios of what cold when go wrong. And if an Installation is interrupted, because the power to the device is cut for some reason, I can't do anything at the moment, but in my eye that's a scenario that the agent could recover from without human interaction.
   But saving the File or the download URL in nonvolatile memory is not an option at the moment. That's why I am asking.

Is it possible to get some information on when the backend service will ignore a reported state?

Like for e.g. when I report an Installed update when the deployment directly in the download phase. Then the device keeps the in progress state.
Or if download succeeded is reported twice, the second time the service won't send the install action. And the device is stuck in this state.

Please refer to this document on the goal state deployment that Device Update uses in the after the public preview refresh release (Feb' 22): https://github.com/Azure/iot-hub-device-update/blob/main/docs/agent-reference/goal-state-support.md
