I got this error (twice) when attempting "guix system init":

Downloading https://mirror.hydra.gnu.org/nar/ciqw5z470c8ihl1kfswj1j3ix6hs092d-module-import (1KiB installed)...
^[[K module-import                                      0B/s 00:00 | 0B transferred
bzip2: Compressed file ends unexpectedly;
perhaps it is corrupted?  *Possible* reason follows.
bzip2: Inappropriate ioctl for device
Input file = (stdin), output file = (stdout)
It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.
You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.
guix substitute: error: corrupt input while restoring '/gnu/store/ciqw5z470c8ihl1kfswj1j3ix6hs092d-module-import' from #{read pipe}#

guix system: error: build failed:
some substitutes for the outputs of derivation `/gnu/store/9h4nc2fdy2dnklc7rnf61d7993dzsnks-module-import.drv' failed
(usually happens due to networking issues); try `--fallback' to build derivation from source


and if I try to manually download https://mirror.hydra.gnu.org/nar/ciqw5z470c8ihl1kfswj1j3ix6hs092d-module-import

I get a zero length file. :(

Can it be that hydra is losing files?
