I found this will most often occur because you have org loaded before
you try to do the upgrade. Basically, org gets confused because of
having an already loaded version while trying to install a new version.

I was seeing this quite often. Once I re-arranged by init file to ensure
that I can do a package upgrade before org is loaded, all works fairly
reliably.

An easy way to 'fix' the problem is to just delete the org-plus-contrib
directory from your ELPA directory, then restart emacs. Your emacs will
probably downlload and install the package during startup. Just make
sure your org setup comes after your package setup.
