Hello there! Since the latest update to 9.4.4, some of us in Guix have been experiencing issues with loading packages that depend on Org [0]. It seems the root of the problem is that (org-release) returns an empty string, you can see this manifesting in this email actually :-). Looking a little deeper, indeed the org-version.el packaged in Guix is as follows: --8<---------------cut here---------------start------------->8--- ;;; org-version.el --- autogenerated file, do not edit ;; ;;; Code: ;;;###autoload (defun org-release () "The release version of Org. Inserted by installing Org mode or when a release is made." (let ((org-release "")) org-release)) ;;;###autoload (defun org-git-version () "The Git version of Org mode. Inserted by installing Org or when a release is made." (let ((org-git-version "")) org-git-version)) (provide 'org-version) ;; Local Variables: ;; version-control: never ;; no-byte-compile: t ;; coding: utf-8 ;; End: ;;; org-version.el ends here --8<---------------cut here---------------end--------------->8--- We download the Org source code directly from ELPA [1], it would seemx the org-version.el wasn't correctly generated, right? Thanks so much for Org!

You don't know how to make a good report? See https://orgmode.org/manual/Feedback.html#Feedback Your bug report will be posted to the Org mailing list. ------------------------------------------------------------------------ Emacs : GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.23, cairo version 1.16.0) Package: Org mode version ( @ /home/pierre/.guix-profile/share/emacs/site-lisp/)
