  Requirements installation failed with status: 100.
  </code></pre>
  
  <p>And then I tried to install libssl-dev.It wasn't installed.. I got this error:</p>
  
  <pre><code>Package libssl-dev is not available, but is referred to by another package.
  This may mean that the package is missing, has been obsoleted, or
  is only available from another source
  
  E: Package 'libssl-dev' has no installation candidate
  </code></pre>
  
  <p>what should I do now?</p>
