I've seen these types of errors before. There must be some way, in the current implementation of the script that generates and signs the base.tar file, that they don't get updated at the same time. I intend to rewrite the script in such a way that ensures an atomic update.

Until then, you can try to force the build again an hour later, by which time there should be a new file.
