cap deploy - getting permission denied - deployment

Question

I am trying to deploy my rails project into sub-domain, but I am getting following error while running cap deploy
[Deprecation Warning] This API has changed, please hook `deploy:create_symlink` instead of `deploy:symlink`.
* 2013-09-27 21:14:44 executing `deploy'

If i am trying to run cap deploy:setup it is displaying something like:

How to fix this problem?

Answer 1

One error is that you defined a URI where host should go. I suspect you have
role :app, "http://anveshnatech.com/edupdu/www"
in your capfile, when you need something like:
role :app, "anveshnatech.com"
or (example)
role :app, "10.1.1.1"
These are probably not be the only errors, you have some permission problems with your git key and some strangeness with deprecation warnings.
