Hello!

> guix substitute: error: download from 'https://mirror.hydra.gnu.org/guix/=
nar/gzip/9xwrnm3vymsf9w17ayc7dfp5cl1aykq5-metis-5.1.0' failed: 504, "Gatewa=
y Time-out"
> substitution of /gnu/store/9xwrnm3vymsf9w17ayc7dfp5cl1aykq5-metis-5.1.0 f=
ailed

The problem is that hydra.gnu.org is currently down=C2=B9 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/9xwrnm3vymsf9w17ayc7dfp5cl1aykq=
5-metis-5.1.0>
is not.

I don=E2=80=99t have a good solution to this other than temporarily removing
mirror.hydra.gnu.org from your substitute URLs.

HTH,
Ludo=E2=80=99.
