Kaushal has now provided a code snippet that can reproduce this in a
cleanly built emacs -Q with a separate .emacs.d. In this test case, the
error shows up when installing the second or third package from the
Package Menu. Curiously, the first installs without a hitch.
It's a bit hard to debug, because the error happens in an async emacs
subprocess.
This code (in paradox-execute.el) is executed in the parent emacs:
(eval
`(async-start
(lambda ()
(require 'package)
,(async-inject-variables "\\`package-")
(setq package-menu-async nil)
(dolist (elt package-alist)
(package-activate (car elt) 'force))
(let ((alist ,(macroexpand
`(paradox--perform-package-transaction
',install-list ',delete-list))))
(list package-alist
(when (boundp 'package-selected-packages)
package-selected-packages)
package-archive-contents
;; This is the alist that will be passed to the hook.
(cons '(noquery . ,noquery) (cons '(async . t) alist)))))
(lambda () ... )))
The first lambda is executed in a subprocess emacs and throws the error
(wrong-type-argument sequencep #s(package-desc swiper ... ))
I'm going to study async.el documentation and code to see if there's a
way to debug this. But if anyone has any hints, that would be appreciated.
