1. restart state file is not being deleted (after image has been restarted)

After a successfully completed firmware workflow, if the tedge-agent service is restarted, then tedge-agent will reprocess the restart-current-operation file again as the file is not deleted after the workflow has been completed.

file: /data/tedge/.agent/restart-current-operation

// cat /data/tedge/.agent/restart-current-operation
{"target":"device/main//","cmd_id":"c8y-mapper-2023-11-26T12:26:39.248420821Z","payload":{"status":"executing","context":{"command":{"topic":{"name":"te/device/main///cmd/firmware_update/c8y-mapper-2023-11-26T12:26:39.248420821Z"},"status":"rollback_restart","payload":{"name":"core-image-tedge-mender-raspberrypi4-64","reason":"Nothing to commit. Either the boot loader triggered the rollback, the device was rebooted after switching to new partition, or someone did a manual rollback!","remoteUrl":"https://t2873877.latest.stage.c8y.io/inventory/binaries/4785008","status":"rollback_restart","

To install a specific version of thin-edge.io on a Debian based operating system, you will have to use APT Package Pinning, as the tedge-full package is a virtual package, and installing a specific version of the virtual package does not transfer to the package's dependencies (unfortunately).

Below shows how the exact thin-edge.io version can be installed.

Create a debian package pin definition for thin-edge.io

Create the following file:

sudo vi /etc/apt/preferences.d/tedge

Updating the location information in Cumulocity IoT should not be a problem with thin-edge.io.

For reference, I created the options by reading the following Cumulocity IoT documentation links:

In summary, updating a location of a device (in the backend) involves creating an event and then updating a fragment on the device's managed object, however you have a few different options on how to achieve this with thin-edge.io:

README

Summary

Upload files to Cumulocity IoT by creating an event and uploading a given file to it.
