bug#36725: 26.1; Emacs can't connect to gnu elpa

[Lennard Henze]

Trying to use "use-package" to install evil-mode. use-package showed:
cant access: https://elpa.gnu.org/packages/undo-tree.html :Bad request
Tryed to package-install w/o use-package: other repos worked,
elpa.gnu.org did not work. tried other repos:
first popkit @ http://elpa.popkit.org/packages/ ... did not work, same
problem
than tried http://elpa.emacs-china.org/gnu/ ... did work, no idea why
https://elpa.gnu.org/packages/undo-tree.html was available the whole
time with curl, and even with emacs built in browser.
dont know if it really is a bug, but i tried trubbleshooting other stuff
on my os (5.2.1-arch1-1-ARCH). First had emacs 26.2, than downgraded to
26.1 bug was in both versions.

Fresh install, only change is .emacs:
(setq package-archives
'(("gnu" . "http://elpa.emacs-china.org/gnu/";)
("melpa" . "https://melpa.org/packages/";)
("org" . "https://orgmode.org/elpa/";)))

(require 'package)
(package-initialize)

(unless (package-installed-p 'use-package)
(package-refresh-contents)
(package-install 'use-package))

(require 'use-package)

(use-package evil
:ensure t
:config
(evil-mode 1))
(custom-set-variables
'(package-selected-packages
(quote
(ghci-completion bnf-mode yasnippet undo-tree use-package))))
(custom-set-faces
)


Hope this helps!
Thanks for doing this :)
