Hey Guixers, i think guix makes the same mistake Nixpkgs make (at least when I looked up what guix is doing around two weeks ago):
They fetch the uncompressed tars built by ELPA. These are only available for the newest version of a package. ELPA keeps compressed archives only of around 20 hand-selected versions. All package versions are kept in their git repo, which is a complete archive, but there you must somehow extract the commit hash of a version. Details are here: - https://github.com/ttuegel/emacs2nix/issues/55 - https://github.com/NixOS/nixpkgs/issues/110796 - https://debbugs.gnu.org/cgi/bugreport.cgi?bug=46441 I proposed possible solutions in the Nixpkgs issue. Best, Johannes
