I load modus-themes (among other packages) in my Emacs configuration using:
(setq package-archives '(("gnu" . "https://elpa.gnu.org/packages/")
("melpa" . "https://melpa.org/packages/")))
(package-initialize)
(unless (package-installed-p 'use-package)
(package-refresh-contents)
(package-install 'use-package))
(eval-when-compile (require 'use-package))
(require 'use-package-ensure)
(setq use-package-always-ensure t)
(use-package modus-themes
:init
;; Add all your customizations prior to loading the themes
(setq modus-themes-slanted-constructs t
modus-themes-bold-constructs t
modus-themes-mode-line nil
modus-themes-region '(bg-only no-extend))
;; Load the theme files before enabling a theme (else you get an error).
(modus-themes-load-themes)
:config
;; Load the theme of your choice:
(modus-themes-load-vivendi))
I upgrade all my packages occasionally by running list-packages then hitting U and x. When I start Emacs next I find that the modus-themes-load-vivendi theme is note active and *Messages* contains:
Error (use-package): modus-themes/:init: Symbol’s function definition is void: modus-themes--standard-completions
Error (use-package): modus-themes/:config: Symbol’s function definition is void: modus-themes--standard-completions
Error (use-package): theme-changer/:config: Symbol’s function definition is void: modus-themes--standard-completions
(although I have historically had other errors too.) The only way I've found to fix these errors is to delete the elpa/modus-themes-* directory so that use-package downloads it again.
I believe that I've seen similar problems with magit, but I no longer have the error messages to prove it.
I've not found anyone else reporting similar problems, so I can only assume that what I'm seeing must be due to something in my configuration, but I don't know where to start looking. The only clue I have is that the .el files for the latest version of modus-themes no longer contains modus-themes--standard-completions yet the byte-compiled .elc files do contain mentions of it despite the timestamps being the same:

Any ideas gratefully appreciated.
