trying to install Flycheck from stable.melpa.org; I get this message
https://stable.melpa.org/packages/flycheck-20160519.303.tar: Not found
I've tried using package-mode, and also the temporary install method (eval-buffer including (package-install 'flycheck), and I keep getting this message.
Thanks
