Still happens with GNU Emacs 27.1 (build 1, x86_64-apple-darwin19.6.0, NS
appkit-1894.60 Version 10.15.7 (Build 19H15)) of 2020-12-02

1. Upgraded all packages
2. Selected one randomly: "package", package was upgraded from 0.5.2 to
0.5.3
3. M-x describe-function (on package-dired)
Cannot open doc string file
"/Users/helehvas/.emacs.d/elpa/project-0.5.2/project.elc"

Cheers,
