title: v4l2loopback cannot load module on aws ubuntu 18.04
body: <p>Currently trying to install v4l2loopback into a ubuntu 18.04 instance at aws and facing the current situation</p>
  
  <p>After running (the same happens from source install)</p>
  
  <pre><code>sudo apt-get install linux-generic (tempts to load videodev)
  sudo apt-get install v4l2loopback-dkms
  sudo modprobe v4l2loopback
  </code></pre>
  
  <p>I have the following error:</p>
  
  <pre><code>modprobe: ERROR: could not insert 'v4l2loopback': Unknown symbol in module, or unknown parameter (see dmesg
  </code></pre>
  
  <p>The same happens for loading <code>videodev</code> (<code>sudo modprobe videodev</code>)</p>
  
  <p>Is there any way to recompile the kernel loading the <code>v4l2</code>/<code>videodev</code> modules? Or any alternative for v4l2loopback on cloud instances?</p>
