Install Org from the "package menu" with M-x list-packages

• See Package Menu

Important: You need to do this in a session where no .org file has been visited, i.e. where no Org builtin function have been loaded. Otherwise autoload Org functions will mess up the installation. This is particularly important given my literate configuration of Emacs using a config.org file.

To "upgrade" Org-Mode the following procedure should be used (given the above description) when using a literate Org-mode configuration for Emacs:

1. Start Emacs without your configuration using the following command:

   emacs -Q
   

2. Run M-x list-packages to browse available packages.
3. Search for Org-Mode using C-s org.
4. Press i to mark the Org package for installation.
5. Press x to install.
6. Use M-x locate-library RET org.

   • If the installation was successful, you should see something like the following:

     Library is file ~/.emacs.d/elpa/org-20110403/org.elc
     

7. Reload Emacs (with your literate Emacs configuration).

   • Rerun M-x locate-library RET org and confirm the installation was successful.

     Library is file ~/.emacs.d/elpa/org-9.7.16/org.elc
