Installing Vidyo on Ubuntu 16.06 LTS (dependency libqt4-gui unmet)

I've recently upgraded to Ubuntu 16.06 LTS from Ubuntu 14.04 LTS.
The only package I've noticed to be missing is vidyodesktop.

In order to install it, I tried going to and open the .deb file.
Unfortunately, it would not install.
In order to determine why it was failing I run this:
sudo dpkg -i VidyoDesktopInstaller-ubuntu64-TAG_VD_3_3_0_027.deb 
Unfortunately it said that libqt4-gui needed to be installed, however. the package is not available for this version of Ubuntu.
In order to fix it, rail told me that we had to install a dummy package to fool Vidyo. This can be accomplished with equivs package.

  • Install equivs package
sudo apt-get install equivs
  • Generate a control file
equivs-control libqt4-gui
  • Edit libqt4-gui and tweak the following variables: Package, Version, Description. Example file
### Commented entries have reasonable defaults.
### Uncomment to edit them.
