When I try to install ac-cider via package-install or via init.el I get the message http://melpa-stable.milkbox.net/packages/popup-20160531.425.el: Not Found:

popup-20160531.425.el: Not Found

This is the code in my init.el:

(require 'package)
;; (add-to-list 'package-archives
;;              '("marmalade" . "http://marmalade-repo.org/packages/") t)
;; (add-to-list 'package-archives
;;              '("tromey" . "http://tromey.com/elpa/") t)
;; (add-to-list 'package-archives
;;              '("melpa" . "http://melpa.milkbox.net/packages/") t)

(setq package-archives '(("gnu" . "http://elpa.gnu.org/packages/")
                         ("marmalade" . "http://marmalade-repo.org/packages/")
                         ("melpa" . "http://melpa-stable.milkbox.net/packages/")))

;; Load and activate emacs packages. Do this first so that the
;; packages are loaded before you start trying to modify them.
;; This also sets the load path.

;; Download the ELPA archive description if needed.
;; This informs Emacs about the latest versions of all packages, and
;; makes them available for download.
(when (not package-archive-contents)

;; The packages you want installed. You can also install these
;; manually with M-x package-install
;; Add in your own as you wish:
(defvar my-packages

How can this be fixed so that ac-cider is installed?

  • Do you see any Messages about failing to download an archive? Jul 13, 2016 at 21:16
  • @JohnKitchin No. Just the message that popup is not found (and therefore fails to download). Jul 13, 2016 at 21:23

It seems that your package archive metadata is corrupted. Try renaming your .emacs.d temporally and re-run with your init.el.

mv ~/.emacs.d ~/.emacs.d-tmp; emacs -Q -l path/to/init.el

I can setup successfully with your init.el pasted above (replacing last defvar with package-install).
