Due to a long-standing bug in the Marmalade software, I was unable to upload the 1.3.0 release of Elpy to that repository in the last two weeks. For a discussion of this problem, see issue #196. To solve this problem, I have created a package archive specific to Elpy with the required packages that are not on GNU ELPA. To use this archive, add the following to your .emacs:
(require 'package)
(add-to-list 'package-archives
'("elpy" . "http://jorgenschaefer.github.io/packages/"))This is intended as a temporary solution, but I am not sure when I have the time to work on a longer-term one. I am sorry for the inconvenience in the last weeks.
