Update broke virtualbox

I know I SHOULD post this to the VirtialBox forum, but take a look at this requirement:

I attempted to create an account, but cannot get a confirmation email. On to the post.
OS: Ubuntu 16.04 64bit with Gnome-Classic
I restarted my computer this morning after an update. Now when I attempt to start andy of my VMs in VirtualBox I receive the following error:

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing
'/sbin/vboxconfig'
as root.
where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

I run the command via sudo and receive this error:

vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: Look at /var/log/vbox-setup.log to find out what went wrong.

There were problems setting up VirtualBox.  To re-start the set-up process, run
  /sbin/vboxconfig
as root.

I have attached the /var/log/vbox-setup.log file.
vbox-setup.log.txt.zip

I am currently stuck and do not know how to fix this.

Thread moved to Virtualisation.

Try booting to the previous kernel as there is a known problem with one version in the 4.4 series in 16.04.

This was discussed in great detail in the thread at https://ubuntuforums.org/showthread.php?t=2415046

This worked. Thanks!
