(I > looked for a way to turn off the build checks, at least.) Part of the 404s you’ve seen are due to a server misconfiguration issue on hydra.gnu.org fixed today. They should be resolved progressively. For instance <https://mirror.hydra.gnu.org/guix/nar/gzip/34qpj0aw01m5x673c5j4kmys7psfl85s-emacs-25.2> (Emacs x86_64, current master) is 200 right now. A temporary workaround is to use --substitute-urls=https://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’.
