Looks like the update failure is caused by an old MQTT extension installation. In the log you can see that the update of roon-extension-mqtt succeeds (new name), but the update of roon-mqtt-extension fails (old name).
Please try the following:
- Uninstall the MQTT extension via the Extension Manager
- Uninstall the old installation by running the following command in a command window:
npm uninstall -g roon-mqtt-extension - Install the MQTT extension again via the Extension Manager
