Hi, After installing the guix on my ubuntu workstation. I am finding the following error when trying to install guix-locales. Apparently, the https://mirror.hydra.gnu.org returns 504 . I am not sure if the server is down or something else is wrong. #+begin_log substitute: guix substitute: warning: while fetching ' https://mirror.hydra.gnu.org/nix-cache-info': 504 ("Gateway Time-out") substitute: guix substitute: warning: ignoring substitute server at '" https://mirror.hydra.gnu.org"' #+end_log Thanks, Rohit
