Spacemacs is unusable, reporting `Symbol's function definition is void: function-alias-p`

[ghost]

Description :octocat:

I updated my packages by pressing SPC f e U and restarted Emacs. Now, Spacemacs is unusable, reporting Symbol's function definition is void: function-alias-p.

I want to Rollback Package Update, but the link cannot be followed by pressing o or clicking it.

Reproduction guide :beetle:

• Start Emacs

Observed behaviour: :eyes: :broken_heart: I see and nothing works.

Expected behaviour: :heart: :smile: Spacemacs works.

System Info :computer:

• OS: gnu/linux
• Emacs: 28.1
• Spacemacs: 0.999.0
• Spacemacs branch: develop (rev. 4a227fc94)
• Graphic display: t
• Running in daemon: nil
• Distribution: spacemacs
• Editing style: vim
• Completion: helm

How can one roll back package updates from outside Spacemacs?

I get the same issue with new clean installation as well. On Fedora with emacs 28.3

Oof, this is probably my fault: I used function-alias-p in a PR I wrote that was recently adopted into bind-map, but it looks like that function was only introduced in emacs 29.1. If you're able to upgrade emacs, that will immediately fix your problem, but I'm going to try to get a patch added to bind-map that will only call that function if it's available.

PR has been speedily merged so this is now fixed in bind-map, and it's now live on MELPA.

Unfortunately, you may still have difficulty upgrading to the fixed version of bind-map since interacting with the "Update Packages" button in the *spacemacs* buffer seems to depend on bind-map. Instead, you can either

• Delete bind-map manually, which should trigger spacemacs to install it fresh from MELPA on the next launch. You can find the folder to delete somewhere like ~/.emacs.d/elpa/28.1/develop/bind-map-20230307.1837.
• Upgrade packages with M-x configuration-layer/update-packages RET

Please confirm that this works, and then we can close the issue. My apologies for causing the problem!

• Upgrade packages with M-x configuration-layer/update-packages RET

This was impossible because M-x did not work. Instead, I deleted .emacs.d and cloned Spacemacs again, and it is working now. Thank you for repairing it.

Yesterday I pressed SPC f e U and broke Spacemacs. I needed then to roll back that update, but could not do so from within Spacemacs. How could I have done so from without Spacemacs? That would have allowed me to use Spacemacs while waiting for the guilty package to be repaired.

I used this method and it worked nicely. In my case it was: rm -r ~/.emacs.d/elpa/27.1/develop/bind-map-20240307.1837/
