Virtualbox does not work after being installed from Software Boutique

[Hjörleifur Jónsson]

Repro
Install Virtualbox from Software Boutique

Virtualbox does not show up in the applications menu

Open terminal and run virtulbox you get the error.

WARNING: The character device /dev/vboxdrv does not exist.
  Please install the virtualbox-dkms package and the appropriate
  headers, most likely linux-headers-generic.

  You will not be able to start VMs until this problem is fixed.

Both packages are installed and probably only a restart is needed for it to work but that is not mentioned anywhere in the install process.

I can confirm this behavior.

A reboot has the effect of having VirtualBox appear in the Menu and work as expected.

Version of VirtualBox 6.0.14_Ubuntur132055

Tested this on Ubuntu 19.10 and Virtualbox is added and works without needing a reboot.

Tested on Ubuntu MATE 19.10 and installed Virtualbox via `sudo apt install virtualbox` and not using the Software Boutique and issue occurs there as well.
