title: How to add an enterprise certificate authority (CA) to git on cygwin (and some linux distros)
body: <p>When fetching with git on Cygwin you get:</p>
  
  <pre><code>Fetching origin
  fatal: unable to access 'https://.../...git': SSL certificate problem: self signed certificate in certificate chain
  error: Could not fetch origin
  </code></pre>
  
  <p>The certificate was added to <code>/etc/ssl/certs/ca-bundle.crt</code> and <a href="https://stackoverflow.com/questions/3777075/ssl-certificate-rejected-trying-to-access-github-over-https-behind-firewall">other bundle files</a>, but on the next Cygwin update the problem reappeared.</p>
