Emacs 无法下载整个 melpa

Question

Hello my emacs cannot download whole melpa

Unable to find theme file for 'solarized-dark'

I add oficial code from melpa webpage and mx package-list-packages and there is only some melpa packages

(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
;; Comment/uncomment this line to enable MELPA Stable if desired.  See `package-archive-priorities`
;; and `package-pinned-packages`. Most users will not need or want to do this.
;;(add-to-list 'package-archives '("melpa-stable" . "https://stable.melpa.org/packages/") t)
(package-initialize)


(load-theme 'solarized-dark t)

Answer 1

if gnu pg key are not imported it will not download whole melpa type:

`alt-x package-install enter use-package enter

this will trigger download gnu pg keys and also use-package is package which must be installed for install other packages
