Hi,
I get a 504 error while installing Octave, even though Octave is built
on my substitute server (cuirass.lassieur.org), and I cleared the cache.
I think it should automatically fallback on another substitute server if
one of them is down.

The problem is that hydra.gnu.org is currently down¹ and
mirror.hydra.gnu.org is just proxying it.
What happens here is that
<https://mirror.hydra.gnu.org/9xwrnm3vymsf9w17ayc7dfp5cl1aykq5.narinfo>
is available (cached), whereas the corresponding
<https://mirror.hydra.gnu.org/guix/nar/gzip/9xwrnm3vymsf9w17ayc7dfp5cl1aykq5-metis-5.1.0>
is not.
I don’t have a good solution to this other than temporarily removing
mirror.hydra.gnu.org from your substitute URLs.
HTH,
Ludo’.

Hi Ludovic,
I don't understand why you closed the bug report. Your explanation of
the bug makes sense, but it doesn't mean that it's fixed.
I expect that when a substitute server is down, for whatever reason,
Guix should still work smoothly if there is another server set up.
If you think there is no way to fix it, maybe the tag "wontfix" would be
more appropriate?
Cheers,
Clément

No I think you’re right, I shouldn’t have closed it.
I think my first thought was that the problem (narinfo available but
corresponding nar missing) was mostly due to our peculiar nginx setup on
mirror.hydra.gnu.org: this cannot happen under normal circumstances
because ‘guix publish’ really honors the expiry it sets on narinfos.
That said, we could fix ‘process-substitution’ in (guix scripts
substitute) to try other nar URLs (if any) upon failure.
IMO such a fix is not “high-priority” for the reason I gave above, but
OTOH it can be helpful to better cope with the sad reality of situations
like the one we’re in.
Thoughts?
Thanks for the heads-up, and sorry for hitting the “close” button too
quickly!

I agree that fixing 'process-substitution' would be nice even though
it's not a high priority issue.

No problem ;) I also removed the "fixed" tag.
