title: ERROR: The certificate of `raw.githubusercontent.com' is not trusted
body: <p>I am trying to use wget to retrieve some file from github over a remote server (ssh), here is what I get:</p>
  
  <pre><code>$ wget  https://raw.githubusercontent.com/aseemk/seadragon-ajax/master/seadragon-min.js

  <p>Same goes for curl:</p>
  
  <pre><code>$ curl -o bla  https://raw.githubusercontent.com/aseemk/seadragon-ajax/master/seadragon-min.js

  More details here: http://curl.haxx.se/docs/sslcerts.html
  
  curl performs SSL certificate verification by default, using a "bundle"
   of Certificate Authority (CA) public keys (CA certs). If the default
   bundle file isn't adequate, you can specify an alternate file
   using the --cacert option.
  If this HTTPS server uses a certificate signed by a CA represented in
   the bundle, the certificate verification probably failed due to a
   problem with the certificate (it might be expired, or the name might
   not match the domain name in the URL).
  If you'd like to turn off curl's verification of the certificate, use
   the -k (or --insecure) option.

  <p>Using wget option: <code>--no-check-certificate</code> seems like a hack, what could I be missing ?</p>
