I've installed azure identity service on my Ubuntu 18.04 and pasted primary connection string on config.toml. After that I've installed azure device update agent (cloned repo and followed this: https://github.com/Azure/iot-hub-device-update/blob/main/docs/agent-reference/how-to-build-agent-code.md) and configured in du-config.json connection type as AIS and cleaned connection string data.
Now, once trying to start device update agent, I get this message:
[E] Failed to set DO connection string in Nested Edge scenario, result: 0x00000000 [StartupAgent]
[I] Agent exited with code 1 [main]
[I] Agent is shutting down with signal 0. [ShutdownAgent]
[I] De-initializing command listener thread [UninitializeCommandListenerThread]
[I] ADUC agent stopping [AzureDeviceUpdateCoreInterface_Destroy]
[I] Calling ADUC_Unregister [ADUC_MethodCall_Unregister]
followed by:
deviceupdate-agent.service: Main process exited, code=exited, status=1/FAILURE
This page: https://github.com/Azure/iot-hub-device-update/issues/209 says that a dependency (do-client) is not creating the directory "/etc/deliveryoptimization-agent" after it's installation (I've installed dependences by: ./scripts/install-deps.sh -a), so I tried creating that dir by my own:
sudo mkdir /etc/deliveryoptimization-agent
sudo chgrp -R do /etc/deliveryoptimization-agent
sudo chown do:do /etc/deliveryoptimization-agent
sudo chmod 0750 /etc/deliveryoptimization-agent
But even so I still get the same error. Unfortunately there is no other clue on which is the issue.
Can somebody help me with this?
