title: How to install cuDNN5.1 with .deb file on ubuntu 14
body: <p>I was trying to install the latest version of cuDNN (5.1) with <code>.deb</code> file. Here are the steps that I tried:</p>
  
  <ol>
  <li>download the .deb file (not tar files found for the latest version)
  libcudnn5_5.1.10-1+cuda8.0_amd64.deb</li>
  <li><code>sudo dpkg -i libcudnn5_5.1.10-1+cuda8.0_amd64.deb</code></li>
  <li><code>sudo apt-get update</code></li>
  <li><code>sudo apt-get install cuDNN</code></li>
  </ol>
  
  <p>The last step failed. I tried with 'cudnn' but, the error is </p>
  
  <blockquote>
    <p>"E: Unable to locate package cuDNN"</p>
  </blockquote>
  
  <p>I am not sure what is the correct package name for the last installation step.</p>
