doubtttttttttttttt
<p>First try to run the command</p>
<pre><code>helm repo update
</code></pre>
<p>and after that try running the command to install the <code>cert manager</code>.</p>
<pre><code>helm install cert-manager jetstack/cert-manager --namespace cert-manager --version v1.2.0 --create-namespace --set installCRDs=true
</code></pre>
<p>For this error</p>
<pre><code>Error: cannot re-use a name that is still in use
</code></pre>
<p>it might be possible <strong>cert-manager</strong> is already running inside the cluster.</p>
<p>Try listing using</p>
<pre><code>helm ls -n &lt;Namespace to check&gt;
</code></pre>
<p><strong>Note</strong> :</p>
<p>it also possible if you had previously installed the <code>cert-manager</code> with helm version <strong>v2</strong> and you are trying to list the all template with helm <strong>v3</strong> it won't show anything.</p>
<p>Make sure helm version is proper.</p>
