Connection to MPD failed

For sure apt-get update && apt-get upgrade from the 6.1.0 release will cause a lot of breakage. IIRC it installs updates to PHP and its configuration files which overwrite the configs that moOde uses thus causing the Integrity check to fail.

Just use the current 6.3.0 image from moodeaudio.org. It has full support for the SIG including the enhanced driver and is built using the latest release of Raspbian Buster Lite (2019-09-26).
