title: Helm not considering my remote repo
body: <p>I am using helm 2.6.1 to deploy a package to my kubernetes cluster. I have created a nexus raw repository to host the packaged helm charts. I also have the index file uploaded to the same.</p>
  
  <pre><code>--charts
   - wordpress-0.1.0.tgz
   - index.yaml
  </code></pre>
  
  <p>However, when I try to do a helm install, it never finds the package. I have tried all the below ways. Any other options to try?</p>
  
  <pre><code>+ helm repo list
