This issue might have some spiciness to it. I have two machines with
identical guix commits and --fallback works on one but not the other.

I thought perhaps there was some hyper-odd race condition going on here
(lifeline is consistently at a higher percent than gibraltar when the
error is detected), but I just had a outlier that seems to disprove
that, where lifeline had the same error with a 97.2% download progress
bar.
