bug#31313: 26.1; gnutls.c: [0] (Emacs) Received alert: Handshake failed

[Eric Hanchrow <eric.hanchrow@gmail.com>]

Put this into /tmp/repro.el

     (setq package-archives
           '(("gnu" . "https://elpa.gnu.org/packages/")
             ("melpa" . "https://melpa.org/packages/")
             ("elpy" . "https://jorgenschaefer.github.io/packages/"))
           )
     (package-list-packages)

Then run "emacs -Q --load /tmp/repro.el".  You'll see

     gnutls.c: [0] (Emacs) Received alert:  Handshake failed

in the echo area; the *Packages* buffer's mode line will say Package
Menu:Loading for ever, and after typing U you will see "Waiting for
refresh to finish...".  Basically packages are now unusable.

This used to work until perhaps a few days or weeks ago; as far as I
know nothing has changed.
