recently, trying to clone a git repo from my debian(jessie) box, i'm facing this:
fatal: unable to access 'https://github.com/foo/bar/': gnutls_handshake() failed: A TLS packet with unexpected length was received.
as mentioned by ubuntu folks i used the git compiled with openssl, and now i get:
fatal: unable to access 'https://github.com/foo/bar/': Unknown SSL protocol error in connection to github.com:443
