virtualbox crash on kernel 4.13.0-26

Virtualbox 5.0.40 is not working with the new kernel (4.13.0-26), but the new version of VBox (5.2) works fine.

Download it from VirtualBox page or add the source to your /etc/apt/sources.list:

deb http://download.virtualbox.org/virtualbox/debian xenial contrib

If you use a different version of Ubuntu than 16.04, use the appropriate name instead of xenial.

Add Oracle public key:

wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -

Update repositories and install virtualbox-5.2:

sudo apt-get update
sudo apt-get install virtualbox-5.2

On one of my laptops, VM didn't want to start before I removed virutalbox-dkms:

sudo apt-get remove virtualbox-dkms

After the update, I had a problem after starting the virtual-machine (see VirtualBox - RTR3InitEx failed with rc=-1912 (rc=-1912)). As suggested in the first comment, it had been fixed with the following call:

sudo /sbin/vboxconfig

There is already a bug report on launchpad. https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1736116

It is our best shot to get this bug fixed.

Temporary, we can

• boot the old kernel 4.10.0-42 from the grub menu (not recommended)

• boot the latest 4.4 LTS kernel from the grub menu, which is still getting security patches

  If it is not already installed: sudo apt install linux-generic

or

• upgrade virtualbox from the oracle sources
