--- Begin Message ---Package: python3-hbmqtt Version: 0.9.6-1.1 Severity: grave Justification: hbmqtt.client.MQTTClient.connect never works Tags: patch upstream The MQTTClient is not useable at all at present.

Their support for the pre-async API based on iterators has ceased, but hbmqtt attempts to do so. Avoiding the context manager does the trick here. Please find a minimal patch fixing the problem attached. In any case, hbmqtt looks quite dead upstream. Maybe replacing it with https://github.com/sbtinstruments/asyncio-mqtt would be better.
