I'm using Spacemacs on a Chromebook using the Linux environment. I had a notification indicated me that a new version of Debian was available, and I launched the upgrade. After that, when launching emacs with Spacemacs, it is written

found 6 new package(s) to install ... refreshing package archive: nongnu [/]

After a few time, there is the following warnings:

Error (use-package): hl-todo/:init: Symbol’s function definition is void: global-hl-todo-mode

Error (use-package): undo-tree/:init: Symbol’s function definition is void: global-undo-tree-mode

It looks like I can continue to use emacs/spacemacs normally, but it took a certain time to launch.

  • when I try to undo an action, it doesn't work and I have the following message : `evil-undo: Symbol’s function definition is void: undo-tree-undo` – AreTaro Jun 18 '22 at 06:06
  • open spacemacs today, and new package installation went good. Had the following messages : `Found 6 new package(s) to install... --> refreshing package archive: nongnu... [4/4] --> installing package: undo-tree@spacemacs-editing... [6/6]` No more problems with undo function. – AreTaro Jun 19 '22 at 02:10

It seems to be something related to updating keys. Try updating gnu-elpa-keyring-update. Here is the command "M-x package-install RET gnu-elpa-keyring-update RET"
