org-mode 9.3 links gnus

[Joseph Vidal-Rosset <joseph.vidal.rosset@gmail.com>]

Hello,

With org-mode  9.3 I have  not solved the  problem of links  for getting
emails in the Archives messages ("Tous les messages");

The following  function in my setup  provide a link that  fails. I quote
it:

;; Merci à  Bob Newell , avec ce code, le lien de l'email est modifié correctement dès l'usage de la fonction refile C-c C-w
  (defun jr/fix-the-link (&rest args)
 (interactive)
 (save-excursion
   (find-file "~/Dropbox/Orgzly/todo.org")
   (goto-char (point-min))
   (while (search-forward "gnus:INBOX#" nil t)
     (replace-match "gnus:\\[Gmail\\]/Tous les messages#"))
   (save-buffer)))
(advice-add 'org-capture-finalize :after #'jr/fix-the-link)

;; si cela échoue, cette fonction peut prendre le relai:

(defun hs/replace ()
   (interactive)
   (goto-char 1)
   (let ((search-invisible t)) (replace-string "gnus:INBOX#" "gnus:\\[Gmail\\]/Tous les messages#")))
(define-key global-map (kbd "C-c r") 'hs/replace)

I get this error message:

gnus-select-newsgroup: Couldn’t activate group \[Gmail\]/Tous les messages: NO (NONEXISTENT) Unknown Mailbox: \[Gmail\]/Tous les messages (Failure) [2 times]


I had not this problem with org-mode 9.1,  and I do not know if there is
a solution, in spite of this message:

Your help is welcome !

Best wishes,

Jo.
