I am trying to install auctex via M-x package-install RET auctex.

Unfortunately after a brief splash of Contacting host: elpa.gnu.org:443,

I end up with the message https://elpa.gnu.org/packages/auctex-12.1.2.tar:Bad Request

On a different machine, this seems to work fine - I don't know where this is going wrong.

The top part of my init.el file currently reads:

(require 'package)
(let* ((no-ssl (and (memq system-type '(windows-nt ms-dos))
                    (not (gnutls-available-p))))
       (proto (if no-ssl "http" "https")))
  (when no-ssl
    (warn "\
Your version of Emacs does not support SSL connections,
which is unsafe because it allows man-in-the-middle attacks.
There are two things you can do about this warning:
1. Install an Emacs version that does support SSL and be safe.
2. Remove this warning from your init file so you won't see it again."))

  (add-to-list 'package-archives (cons "melpa-stable" (concat proto "://stable.melpa.org/packages/")) t)
  (when (< emacs-major-version 24)
   ;;  For important compatibility libraries like cl-lib
    (add-to-list 'package-archives (cons "gnu" (concat proto "://elpa.gnu.org/packages/")))))

(package-initialize)

Any ideas as to what I should try? This is Emacs 26.2 btw.

  • @Drew OK, trimmed it down a bit further. – nonreligious Aug 16 at 7:43

Elpa seems to be having issues again. (Reddit discussion.)

Maybe try adding

(setq gnutls-algorithm-priority "NORMAL:-VERS-TLS1.3")

to your config as mentioned here.

  • OK, this worked. Not very familiar with Elpa but it seems strange that the issues in the Reddit post occurred a month ago and it still hasn't been resolved. – nonreligious Aug 17 at 0:43
