title: Unable to locate package python-pip Ubuntu 20.04
body: <p>I am trying to install mininet-wifi. After downloading it, I have been using the following command to install it:</p>
  
  <pre><code>    sudo util/install.sh -Wlnfv
  </code></pre>
  
  <p>However, I keep getting the error:</p>
  
  <pre><code>    E: Unable to locate package python-pip
  </code></pre>
  
  <p>I have tried multiple times to download python-pip. I know mininet-wifi utilizes python 2 instead of python 3. I have tried to download python-pip using the command:</p>
  
  <pre><code>    sudo apt-get install python-pip
  </code></pre>
  
  <p>But that leads to the same error:</p>
  
  <pre><code>    E: Unable to locate package python-pip
  </code></pre>
