Debugger entered--Lisp error: (void-variable \.\.\.)

[liar666]

I confirm that...

• [X] I have searched the issue tracker, documentation, FAQ, Discourse, and Google, in case this issue has already been reported/resolved.

• [X] I have read "How to Debug Issues", and will use it to provide as much information about this issue as possible.

• [X] The issue can be reproduced on the latest available commit of Doom.

• [X] The issue can be reproduced on a stable release of Emacs, such as 27, 28, or 29. (Unstable versions end in .50, .60, or .9x)

Expected behavior

doom sync -u / doom upgrade should work flawlessly

Current behavior

After doom sync -u running emacs --debug-init shows:

Steps to reproduce

1. Run doom sync -u / doom upgrade
2. start emacs --debug-init
3. See error Debugger entered--Lisp error: (void-variable \.\.\.) and things related to font-spec :name "Symbola:"

I had this issue also. Reinstalling Doom fixed it. Specifically, in my case I ran rm -rf $DOOMLOCALDIR; doom install.

I just ran into the same error. No idea what caused it, but commenting out the unicode module in $DOOMDIR/init.el and running doom sync allowed me to restart Emacs without doing a full reinstall.

I did try re-installing the unicode module afterwards, but it went back to same Debugger entered--Lisp error: (void-variable \.\.\.) error on startup, so I have to leave it uninstalled for now.

Update: deleting the cache file ~/.emacs.d/.local/cache/pcache/unicode-fonts and restarting emacs fixed the issue for me.

Digging into the unicode-fonts-setup function from the stacktrace, I found that the issue was the bad void-variable \... being persisted in the unicode-fonts--instructions cache. It looks like the same issue as #5671.

I don't know how that bad value was added to the var originally, but removing the cache file allowed the correct values to regenerate. Eval-ing (unicode-fonts-setup unicode-fonts-fontset-names t) should also force the cache to regenerate.
