This could related to <https://issues.guix.gnu.org/46330>.

Is it still happening, consistently?  Or did you eventually manage to
download that substitute?

I tried just in case but couldn’t reproduce it.  What matters here is
the guix-daemon in use (which store item?), but I suspect it’s
non-deterministic anyway.

Thanks,
