title: Failure installing sbt: "Server access Error: java.security.cert.CertificateException:"
body: <p>When I try to install error messages, it fails to download. I get error messages like this:</p>
  
  <pre><code>[error] Server access Error: java.security.cert.CertificateException: No subject alternative DNS name matching repo.scala-sbt.org found. url=https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/com.typesafe.sbt/sbt-pgp/scala_2.10/sbt_0.13/0.8.3/ivys/ivy.xml
  </code></pre>
  
  <p>I can confirm, when accessing via my browser, that the certificate installed for the domain <code>repo.scala-sbt.org</code> is actually the certificate for <code>repo.typesafe.com</code>, and this seems to be the source of the error. It doesn't appear to be a DNS issue as <code>http://repo.scala-sbt.org/</code> (insecure) works.</p>
