Ok, I checked the md5sum of filesystem.squashfs against md5sum.txt, and they were different, so, I assume that, at some stage, an error has crept in. I downloaded a later release and pushed it into the stick, and installing gave me a different error, of which I made a new error report. I guess this one could be closed.
