;; it is insufficient to simply correct it with the latest commit.
;; Instead, please push one commit that rolls back Guix to before the mistake,
;; and then another that points to the first one. That way, the faulty commit
;; won't appear on the linked list.
;;
;; If you are updating this package because it fails to build, you need to
;; actually update it *twice*, as the installer is pointing to the N-1 guix
