[Bug 1397685] Re: git gnutls_handshake() failed: A TLS packet with unexpected length was received.

[Nikos]

git.kernel.org is configured to only allow TLS with elliptic curve
ciphersuites. Given that gnutls 2.12.x doesn't support elliptic curves,
it cannot connect to that site.

Bug description:
  Platform: Ubuntu 14.04, ppc64le (Power 8 LE), git version: 1:1.9.1-1
  When accessing a public repository over HTTPS, I get the following error:
  $ git clone --no-checkout https://git.fedorahosted.org/git/lvm2.git lvm2
  Cloning into 'lvm2'...
  fatal: unable to access 'https://git.fedorahosted.org/git/lvm2.git/': gnutls_handshake() failed: A TLS packet with unexpected length was received.

  Accessing the same public repository from a different machine running
  in a different network - also Ubuntu 14.04, but running on x86-64, the
  commands executed with no errors. Both platforms have the same git
  version (dpkg -l | grep git)

  I checked online for an explanation. Found this:
  http://askubuntu.com/questions/186847/error-gnutls-handshake-falied-when-connecting-to-https-servers

  According to that, Gnu TLS may have some issues when proxies
  (firewalls?) are present on the network path to the repositories. The
  recommended solution is to rebuild git using OpenSSL instead of TLS. I
  tried it and got to a different error ("Unknown SSL protocol error").

  Can you please fix git to make it work correctly?
