Why is the host key failing?

[chris]

Is it a mismatch between the git server and deployment server? I have
the same public key on the git server and the web server. Is there
something more that I need?

Thanks for the help

Github changed their ssh host-key a while back, I believe.
If you remove the old line from .ssh/known_hosts that is shown when
you do ssh g...@github.com.
That should fix the problem.

You could probably check whether the ssh connection to github is
working by doing the following,
$ cap ROLES=app COMMAND="ssh g...@github.com" invoke

It should return something like:

Thanks Tim,

I should've just ready the instructions (http://github.com/guides/
deploying-with-capistrano) github provides. I was missing a couple
things.

All is good now.
