[Freedombox-pkg-team] Bug#863740: pagekite: Fail to connect to pagekite, claim invalid ssl cert

Wed May 31 11:34:18 UTC 2017

I asked upstream about this.  Bjarni suggested it perhaps was related to
the use of StartSSL certificates and pointed me to
<URL: http://pagekite.net/2016-11-22/Pagekite_py_0_5_9,_CA_trust_issue >.

I tested by using the StartCom/StartSSL CA certificates, and it did
indeed solve the problem.  I guess Debian removed the relevant
certificates from Stretch?  This changelog from ca-certificates seem
relevant, but I do not quite understand what the effect of the change
is:

ca-certificates (20161130+nmu1) unstable; urgency=medium

  * Non-maintainer upload.
  * Add StartCom and WoSign certificates to mozilla/blacklist.txt as they are
    now untrusted by the major browser vendors. Closes: #858539

I am not quite sure exactly which certificate is used, but this is the
change I implemented to solve the problem.
