title: Helm can't find chart
body: <p>I've published my chart to chartmuseum. And yes, I've ran "helm repo update".</p>
  
  <pre><code>$ helm search chartmuseum/
  NAME                        CHART VERSION   APP VERSION DESCRIPTION            
  chartmuseum/whoami          1-master                    A Helm chart for whoami
  chartmuseum/whoami-master   0.0.1-SNAPSHOT              A Helm chart for whoami
  chartmuseum/whoami-release  0.0.1-SNAPSHOT              A Helm chart for whoami
  </code></pre>
  
  <p>But when I try to find it...</p>
  
  <pre><code>$ helm install chartmuseum/whoami-release
  Error: failed to download "chartmuseum/whoami-release" (hint: running `helm repo update` may help)
  </code></pre>
  
  <p>Anyone got a clue about what I do wrong?</p>
