title: Intalling libqwt6 on Ubuntu 16.04
body: <p>Good Day to you,</p>
  
  <p>I have a program to install which needs the library libqwt6. I am installing it using a .deb package. In previous versions of Ubuntu, it seems that this library could be installed with a simple apt-get but for my version, no package correspond to that name. </p>
  
  <p>So I tried to install the library by first installing QT to then be able to install <a href="http://qwt.sourceforge.net/#installonmainpage" rel="nofollow noreferrer">Qwt</a>. After having done that, I have a file libqwt.so on my disk. I added it to the dynamic linker but the system still cannot find it. When I look for libqwt with :</p>
  
  <pre><code>ldconfig -p | grep libqwt
  </code></pre>
  
  <p>I get</p>
  
  <pre><code>libqwt6 (libc6)
  </code></pre>
  
  <p>Does anyone have a simple solution to install this library? Would returning to an older version of Ubuntu be the best way? </p>
