bug#71356: use-package doesn't load org from elpa

[Pedro Andres Aranda Gutierrez]

Hi, 

Andrea is right. Reading through all the documentation, I implied

that use-package would upgrade built-in packages if I pinned them to an archive

and I :ensure'd them. 

Use case: want to upgrade org from the 9.6.x version packaged with master to the

9.7.x version available in elpa. 

Maybe this is more a FR and if so, we could move this to the list and have an informed 

discussion there.

Best, /PA

I see thanks, OTOH this report is about the use-package macro not
package itself.

use-package doc doesn't mention built-in packages, but describes the two
keyword parameters as:

:ensure          Loads the package using package.el if necessary.
:pin             Pin the package to an archive.

So I found reasonable that for the reported case the user expects the
package to be loaded using package.el.  But as I mentioned I'm no expert
in this area so I might very well be off :)

Thanks
