body: <p>I made a mess out of my self. 
  I wanted to add python3.6 in my system so I decided to uninstall the existing one in my Ubuntu 19.10 . But now everytime I want to install something I get error like this:</p>
  
  <blockquote>
    <p>dpkg: error while cleaning up:
     installed python3-virtualenv package post-installation script subprocess returned error exit 
     status 127</p>
    
    <p>Errors were encountered while processing:python3-virtualenv</p>
    
    <p>Processing was halted because there were too many errors.
    E: Sub-process /usr/bin/dpkg returned an error code (1)</p>
