Can't install use-package to Emacs 27.1 (void-function: (lisp-data-mode)) on Rocky Linux

[emakei]

autoload-generate-file-autoloads: use-package-pkg.el:0:0: error: void-function: (lisp-data-mode)

Just try M-x package-install RET use-package

I am not a emacs expert, but leaving this for the next poor soul that runs into this.. I was able to work around this issue using this hack

(unless (or (fboundp 'lisp-data-mode)
            (not enable-local-variables))
  ;; Work around the fact that transient's autogenerated package header declares mode:
  ;; lisp-data, which is only present in Emacs 28+, thus breaking the loading of deps
  (message "Old Emacs version, remapping lisp-data-mode")
  (defalias 'lisp-data-mode 'emacs-lisp-mode))

This sounds like either:

• https://bugs.gnu.org/76264
  on GNU ELPA; or
• New -pkg.el header causing lisp-data-mode undefined in CI for older versions of Emacs? melpa/melpa#9193
  on MELPA.

Both should be fixed, modulo waiting for affected packages to be rebuilt.
Either way, it doesn't look specific to use-package.

Is this still an issue? If so, please provide more details about your Emacs version, configured package archives, packages being installed, etc.
