<mdeslaur> I haven't looked at it yet, but it's probably an out of order cert, and you're hitting the well known gnutls issue with out-of-order certs
<mdeslaur> xnox: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=573736 , http://lists.gnutls.org/pipermail/gnutls-devel/2013-July/006389.html
<ubot5> Debian bug 573736 in libgnutls26 "permit incorrectly sorted server certificate chains" [Wishlist,Open]
<mdeslaur> xnox: I was sure we had a bug in ubuntu about it, but can't find it now
<mdeslaur> xnox: I haven't checked if that's the case with 01.org yet, but I suspect that's the issue
<mdeslaur> xnox: it's an annoying bug, and people keep hitting it...the patch backport in that thread looks simple enough...just need to make sure it's doing the same as 3.x
<mdeslaur> xnox: I can't find any open ones...there was bug 1043376

Title:
  gnutls26 does not accept out of order certificate chains, whilst
  gnutls28 & openssl do

Status in “gnutls26” package in Ubuntu:
  Confirmed

Bug description:
  gnutls fails to connect to https://01.org in trusty

  In the certificate chain the top level certficate is trusted and is in
  /etc/ssl/certs/ca-certificates.crt, and gnutls-cli (3.x based) in
  utopic and openssl connect to 01.org just fine.

  gnutls-cli (2.6 based) in trusty does not.

  Good:

  Bad:
   gnutls-cli -V --x509cafile /etc/ssl/certs/ca-certificates.crt 01.org     
  Processed 164 CA certificate(s).
  Resolving '01.org'...
  Connecting to '198.145.11.105:443'...
  *** Verifying server certificate failed...
  *** Fatal error: Error in the certificate.
  *** Handshake has failed
  GnuTLS error: Error in the certificate.

  
  Thus anything that talks to 01.org over https using gnutls (e.g. git with libcur(gnutls)) fails to verify certificates and thus does not work in Trusty.
