title: PGP: Not enough random bytes available. Please do some other work to give the OS a chance to collect more entropy
body: <p>Setup : Ubuntu Server on Virtual Machine with 6 cores and 3GB of RAM.</p>
  
  <p>when I am trying to generate a <code>asymmetric key pair</code> via <code>GPG</code> like this <code>gpg --gen-key</code> . I get the following error :</p>
  
  <pre><code>Not enough random bytes available.  Please do some other work to give
  the OS a chance to collect more entropy!
  </code></pre>
  
  <p>I tried to google a little bit. This is what I realise , 
  I need to fire up another terminal and type in <code>cat /udev/random</code> --> It randomly generates a series of randomly generated values to increase the entropy. </p>
  
  <p>I dont see any change in here <code>watch cat /proc/sys/kernel/random/entropy_avail</code></p>
  
  <p>and it still persists to give me the same error</p>
