<p>I am using <code>helm upgrade xyz --install</code> command and my release were failing due to other helm issues. So no successful release is done yet.</p>
<p>Then one time when the above command was in progress, I pressed <code>ctrl+c</code> command. And since then it is showing <code>Error: UPGRADE FAILED: another operation (install/upgrade/rollback) is in progress</code> whenever I try <code>helm upgrade again</code>.</p>
<p>When i do helm history <code>helm history xyz</code> It shows <code>Error: release: not found</code>. No I don't know how to roll back the previous operation so that I can try helm upgrade again.</p>
<p>I tried --force too <code>helm upgrade xyz --install --force</code> but it is still showing <code>some operation is in progress.</code></p>
<p>So how can I roll back the previous process when I don't have any successful release.</p>

<p>The solution is to use <code>helm rollback</code> to restore your previous revision:</p>
<pre><code>helm rollback &lt;name&gt; &lt;revision&gt;
</code></pre>
