Carthage: Authenticity of host 'github.com' can't be established

[danscan]

While running carthage update, I keep getting an error after the check out phase, saying:

The authenticity of host 'github.com (192.30.252.129)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? The authenticity of host 'github.com (192.30.252.128)' can't be established.

Are you sure you want to continue connecting (yes/no)? 

Which doesn't take any input.

Are you using git clone URLs in your Cartfile? Have you tried using HTTPS ones instead?

[danscan]

I fixed it by adding an ssh key to my github account, but the issue needs to be clarified for those who run into the issue in the future, as there's no feedback.

@robb I'm using the standard `"git {owner}/{repo_name}" syntax

AFAIK, this issue would only come up if you don't have a valid certificate for github.com (or perhaps its CSA) already.

Still, maybe we could “fix” this by telling Git that it's not running in an interactive terminal. The goal would be to make Carthage bail out rather than wait for input.

Closing in favor of #219.
