[Bug 1444656] Re: GnuTLS TLS 1.2 handshake failure
This seems like a bug that should be fixed in the LTS rather than
requesting a backport. The 3.2.11 version is available in trusty, but
it's only community supported and doesn't have the utilities built since
it's not the officially supported version. The version with 5 year
support from Canonical is the old 2.12 version gnutls28 (3.2.11) has a
lot of reverse dependencies, so a backport is non trivial. Let's see if
the bug can be fixed in the older version.

Bug description:
I'm experiencing the same issue as here:
http://comments.gmane.org/gmane.network.gnutls.general/3713
I came across a SSL handshake problem with gnutls-cli when connecting to
some websites, see below. It is somehow specific to gnutls as
openssl/Chrome/Firefox can connect fine.
Is this is a bug in gnutls or do you have any ideas how to
troubleshoot it?
$ gnutls-cli --version
gnutls-cli (GnuTLS) 2.12.23

Thank you,
Please back port the latest GnuTLS to Trusty as it is an LTS release and clearly GnuTLS 2.12 is an old branch.
I've also attached packet captures of this.
