Ubuntu 16.04 LTS and VirtualBox 5.1.8

I would like to make create a few Virtual machines, but Virtual Box gives this error message when I start it:

WARNING: The vboxdrv kernel module is not loaded. Either there is no module
     available for the current kernel (4.4.0-45-generic) or it failed to
     load. Please recompile the kernel module and install it by

    sudo /sbin/vboxconfig

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

And so I run sudo /sbin/vboxconfig. Output:

vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find   out why.
There were problems setting up VirtualBox.  To re-start the set-up process, run
/sbin/vboxconfig
as root.

Messages selected as Errors on dmesg :
