That's great!
I guess I ran into this because I was using `guix build` with
`--no-substitutes`. Is it expected that we don't fallback to disarchive
and Software Heritage in that case? If so, I guess my problem was an
operator error. Can we close this ticket then, or are we still missing the
tarballs for the older releases?
Best,
Jack
