title: Flutter doctor failed
body: <p>I installed Flutter on ubuntu 20.04 with &quot;sudo snap install flutter --classic&quot;. after installation I run the flutter doctor. Unfortunately my internet was disconnected and I re-run &quot;flutter doctor&quot; command but i received below error:</p>
  <blockquote>

  <p>I tested some solutions. for example, I removed flutter and reinstalled it. But I have the error yet.</p>
