                Solve freezing of Ubuntu 16.04 (kernel 4.13.0-26) with VBox
              
          
    Fixing freeze at startup - VBox

After last Ubuntu 16.04 kernel update (4.13.0-26), Virtual Box stopped working correctly. When starting a virtual machine, the host stops completely.
Here are the steps to solve it.

Remove any previous virtualbox installation (VM's are kept):
sudo apt-get remove virtualbox virtualbox-5.1
Remove virtualbox-dkms:
sudo apt-get remove virtualbox-dkms
Add the Oracle repository
