It happened to me yesterday and I spoke to wishmaster, I thought it was only affecting the debug symbols version. Seems it affected all of them.
I did try updating just now however and it seems that the 32bit (nightly, no debug symbols) version doesn't wanna update. The other ones (stable and nightly with debug symbols) are working just fine.
The error seems to be a missing file with hashes:
