title: Racket hangs on Google Colab
body: <p>Google Colab is good, runs not just Python, C++, and other langs too thru' the <code>%%script</code> blockmagic.</p>
  
  <p>I'm trying to run Racket but it doesn't work, it hangs. Here's the content to run in Colab:</p>
  
  <pre><code>!sudo apt update -y
  !sudo apt upgrade -y
  !sudo apt install racket -y
  #OK until here.
  
  #Racket supposed to print out version,
  #but it hangs here:
  !racket -v
  </code></pre>
  
  <p>Anyone with a solution? any work-arounds?</p>
