Here I see more than just a warning, in Emacs versions 24 through 27:

0. cd "$(mktemp -d)"
1. HOME="$PWD" XDG_CONFIG_HOME="$PWD" emacs-27.2
2. M-: (setq package-check-signature nil) RET
3. M-x toggle-debug-on-error RET
4. M-x package-install RET dash RET

I attach backtraces from Emacs 24.5 and 27.2.

What I'm not sure about is why only some packages result in an error.
I'm guessing elpa.gnu.org is caching -pkg.el files of packages that have
not been updated in the meantime.

I assume we want to continue supporting older Emacs versions, so does
the elpa.git patch need reverting (plus manual intervention to revert
any cached -pkg.el files), or am I missing something / is there a better
solution?

Thanks,
