Can't clone a development branch

Question

I would like to install typerex from its development branch. But I have trouble in cloning it as follows:

~:~$ git clone git@github.com:OCamlPro/typerex.git
Cloning into 'typerex'...
The authenticity of host 'github.com (204.232.175.90)' 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)? yes
Warning: Permanently added 'github.com,204.232.175.90' (RSA) to the list of known hosts.
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

Does anyone know what to do?

Answer 1

You are trying to access the SSH address without a valid SSH key. Try cloning the read-only address instead. It does not require any authentication of any kind.

git clone git://github.com/OCamlPro/typerex.git
