<p dir="auto">I ran into the same problem described into <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="158039533" data-permission-text="Title is private" data-url="https://github.com/kubernetes/kubernetes/issues/26673" data-hovercard-type="issue" data-hovercard-url="/kubernetes/kubernetes/issues/26673/hovercard" href="https://github.com/kubernetes/kubernetes/issues/26673">#26673</a> but now it's happening on every deploy.<br>
I would have reopened the issue, but I was not the author so I could not.</p>
<p dir="auto">The bug presents itself because I have a build that does <code class="notranslate">kubectl rollout status deployment/application-unstable</code> just after a <code class="notranslate">kubectl apply -f &lt;new deployment manifest&gt;</code> and it gets stuck forever because the rollout is never reported as finished (it does finish tho).</p>
