I've now had it quite a couple of times, so lets note it down here also:
Once in a while, which usually happens once Microsoft ships a new version of one of the underlying dependencies, my build will fail with the following error:

As discussed on another thread (https://github.com/Azure/iot-hub-device-update/issues/83) the issue seems to be that some part of the sstate-cache is not handled correctly, because after running a clean-sstate on various recipes of this meta-layer, it works again:
