Subject: 25.2.2 gpg error upon listing packages; auctex not located in repos
Date: Wed, 4 Dec 2019 16:01:03 -0500

I'm running Ubuntu 18.04.3 LTS, with that distro's standard emacs distribution, 25.2.2.

Problem: running

M-x package-list-packages

results in a gpg error:

--- cut here ---

Failed to verify signature archive-contents.sig:
No public key for 066DAFCB81E42C40 created at 2019-12-02T18:00:02-0500 using RSA
Command output:
gpg: Signature made Mon 02 Dec 2019 06:00:02 PM EST
gpg:                using RSA key C433554766D3DDC64221BFAA066DAFCB81E42C40
gpg: Can't check signature: No public key

--- done ---

I believe this might be the reason why the package listing then fails to display auctex. I can find other, auctex-related packages, e.g.

auctex-latexmk     20170618.1636 incompat   melpa      Add LatexMk support to AUCTeX

They are nevertheless marked 'incompat' and clicking one (the one above for instance) results in a notification as below:

--- cut here ---

Status: Incompatible because it depends on uninstallable packages.
    Archive: melpa

    Version: 20170618.1636
    Summary: Add LatexMk support to AUCTeX
   Requires: auctex-11.87 (not available)
   Homepage: https://github.com/tom-tan/auctex-latexmk/
   Keywords: [tex]

--- done ---

My package repo section in .emacs reads

--- cut here ---

                          ("gnu" . "http://elpa.gnu.org/packages/")
                          ;;("marmalade" . "http://marmalade-repo.org/packages/")
                          ("melpa" . "http://melpa.milkbox.net/packages/")))
;; adds repository for org mode
(require 'package)                                                                                    
(add-to-list 'package-archives '("org" . "http://orgmode.org/elpa/") t)
(package-initialize)

--- done ---

On a different system I got around this by compiling the nweest emacs from source[0], but it would be good to figure out what's going on. I've had this happen on other systems running pre-26 emacsen.

I can reproduce this on an 18.04 LTS.  emacs -Q:

Failed to verify signature archive-contents.sig:
No public key for 066DAFCB81E42C40 created at 2020-08-02T09:05:02+0000 using RS\
A
Command output:
gpg: Signature made Sun Aug  2 09:05:02 2020 UTC
gpg:                using RSA key C433554766D3DDC64221BFAA066DAFCB81E42C40
gpg: Can't check signature: No public key

But I vaguely recall that there was something about an expiring key that
made things not work?  In that case, there isn't much to be done here.

Does anybody remember?

For what it's worth, this has been broken on Ubuntu 18.04 for just about ever.. On all of my Ubuntu machines I simply build the emacs-27 branch from source[0]. 

It's been working fine for months (I forget when the problem first manifested).

Yup:

So I don't think there's anything to be done in this bug report, and I'm
closing it.
