Helm V3 - Cannot find the official repo : <p>I have been trying to install nginx ingress using helm version 3</p>

<pre><code>helm install my-ingress stable/nginx-ingress
</code></pre>

<p>But Helm doesn't seem to be able to find it's official <code>stable</code> repo. It gives the message: </p>

<blockquote>
  <p>Error: failed to download "stable/nginx-ingress" (hint: running <code>helm
  repo update</code> may help)</p>
</blockquote>

<hr>

<p>I tried <code>helm repo update</code>. But it doesn't help.</p>

<p>I tried listing the repos <code>helm repo list</code> but it is empty.</p>

<hr>

<p>I tried to add the stable repo: </p>

<pre><code>helm repo add stable https://github.com/helm/charts/tree/master/stable
</code></pre>

<p>But it fails with: </p>

<blockquote>
  <p>Error: looks like "<a href="https://github.com/helm/charts/tree/master/stable" rel="noreferrer">https://github.com/helm/charts/tree/master/stable</a>"
