Part of the 404s you=E2=80=99ve seen are due to a server misconfiguration i=
ssue
on hydra.gnu.org fixed today.  They should be resolved progressively.
For instance
<https://mirror.hydra.gnu.org/guix/nar/gzip/34qpj0aw01m5x673c5j4kmys7psfl85=
s-emacs-25.2>
(Emacs x86_64, current master) is 200 right now.

A temporary workaround is to use
--substitute-urls=3Dhttps://hydra.gnu.org, which can trigger a
regeneration of the missing archives.  However use with care because
that poor machine is already loaded.

HTH,
Ludo=E2=80=99.
