Package: emacs,org-mode Version: 25.3 emacs -Q -f list-packages
The built-in Org mode is not listed. (This eg causes org-edna to be listed as uninstallable.) Adding a Version: header comment to lisp/org/org.el would fix this. (There was one prior to Emacs rev 8223b1d233.) Obviously it would need to be kept in sync with org-version.el. Ref: http://lists.gnu.org/r/emacs-devel/2018-01/msg00813.html
