Yea, it's clearly corrupted - the file is empty. I don't understand how that
can happen, particularly without any visible error. I certainly can't
reproduce it when installing the packages exactly the same way it happens for
the image.
I also don't think this happened before, despite the recipe for building the
images not having meaningfully changed in quite a while. So it must be some
rare edge case.

I did trigger a rebuild of the image just now. Hopefully that'll fix it.
