I'm trying to use use-package in my Preferences.el file under Aquamacs 3.6. Every time I try to run Aquamacs with the following Preferences.el, Aquamacs hangs, usually indefinitely.

(require 'package)
(add-to-list 'package-archives '("gnu"   . "https://elpa.gnu.org/packages/"))
(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/"))

(package-initialize)

(unless (package-installed-p 'use-package)
  (package-refresh-contents) ;; Does not hang if this line is commented out
)

Does anyone know what is wrong? Incidentally, if I comment out the (package-refresh-contents) line, then Aquamacs starts correctly. Ultimately, I want to install use-package and use it within the remainder of my Preferences.el.

  • Which part of your init file causes it to hang? If you don’t know, try commenting out top–level expressions until the hang goes away.

  • @db48x It appears to be (package-refresh-contents) that causes the hang. I've revised the code above.

  • For how long does it hang? Maybe it is just downloading a large list of packages. strace it and find out what it is doing while it is hung.

    @db48x Thanks for your help! I used open -n /Applications/Aquamacs.app --args --debug-init, which allowed me to see that Aquamacs was prompting me to decide whether to ignore expired certificates from melpa and gnu. After ignoring, Aquamacs now boots promptly.

  • Nice. You should add that as an answer.

I turns out that the cause of Aquamacs hanging was that it was waiting for an answer to a prompt about ignoring expired certificates from melpa and gnu. To discover this, I used

open -n /Applications/Aquamacs.app --args --debug-init

After choosing to ignore, Aquamacs now boots promptly.
