I'm trying to install Virtualbox on my desktop:

Processor: AMD FX(tm)-8350 Eight-Core Processor × 8
OS type: 64bit
Ubuntu 16.04

Here's a snapshot of my bash history:

35  sudo dpkg -i /home/andy/Downloads/virtualbox-5.0_5.0.20-106931~Ubuntu~xenial_amd64.deb 

36  sudo apt-get install libqt4-opengl

37  sudo apt-get -f install

38  sudo apt-get install linux-headers-generic

39  sudo /etc/init.d/vboxdrv setup

40  virtualbox

41  sudo /sbin/rcvboxdrv setup

42  dmesg | grep VirtualBox

43  sudo apt-get install linux-headers-generic build-essential

44  sudo modprobe -v vboxdrv

45  dmesg

46  sudo systemctl status vboxdrv

Expanding on those commands a little:

$ sudo apt-get -f install

$ sudo /etc/init.d/vboxdrv setup

sudo: /etc/init.d/vboxdrv: command not found



$ virtualbox

WARNING: The vboxdrv kernel module is not loaded. Either there is no module

         available for the current kernel (4.4.0-22-generic) or it failed to

         load. Please recompile the kernel module and install it by



           sudo /sbin/rcvboxdrv setup



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

$ dmesg

[ 5845.992334] capability: warning: `VirtualBox' uses 32-bit capabilities (legacy support in use)

So the 'modprobe vboxdrv failed' is problematic. A Google reveals a similar story over here: https://www.virtualbox.org/ticket/11577

I checked my BIOS, in CPU Configuration / SVM this is set to 'enabled'.

This secure virtual mode will let you run multiple OS (guest) on the same physical hardware with the hypervisor layer.

Despite all this VMs still won't launch?

Thwarted by modprobe vboxdrv kernel modules argh!

Any ideas?

1) Disable the secure boot on your BIOS settings : Secure boot prevent unsigned modules to be loaded.

2) According to Virtualbox-wiki you need to install dkms module:

Ubuntu/Debian users might want to install the dkms package to ensure that the VirtualBox host kernel modules (vboxdrv, vboxnetflt and vboxnetadp) are properly updated if the linux kernel version changes during the next apt-get upgrade.

Type the following command to install dkms:

sudo apt-get install dkms

Then you can install Virtual-box following the steps described on Virtualbox/Wiki

For Ubuntu 16.04LTS kernel module 4.4.0-22-generic I had to run:

sudo apt-get install virtualbox-dkms.

In my case it was asking to disable secure UEFI. As a side note, the password requested for confirmation needs to be at least 8 characters long.
