Virual box crash with kernel update

[JimA]

This morning I got a kernel update for Ubuntu 14.04 to 3.19.0-49.

I could not run any of my virtual machines. To fix this I had to reinstall the .deb file for virtualbox 5.0.

Is this normal?

This usually indicates you do not have dkms installed that works to keep kernel modules up to date when a new kernel is installed or that dkms if installed is not working properly.
It also depends on what VirtualBox is installed ( Repo versus official builds ).

I have dkms install for sure. It gave me a command I could run as root '/sbin/rcvboxdrv setup'

It failed with the error' Bad Argument setup'

I'm running the latest linux virtualbox-5.0_5.0.14-105127~Ubuntu~trusty_amd64.deb

If I close VB and reinstall the .deb, I can get it working again.

Still you don't say if you installed from the Repo or from VirtualBox.

The bad argument is only a part of the warning and I would need to complete warning to say what it might be.

I installed from virtualbox website. got the latest .deb and extensions. I did the prerequisites

sudo apt-get install dkms

I double-clicked on the .deb file downloaded from the website and installed.

then doubled clicked on the extensions and installed.

then sudo usermod -a -G vboxusers username

The only text put on the screen was ' Bad Argument setup' when I ran /sbin/rcvboxdrv setup

I suspect this has to do with the change from init.d to systemv Some have a carry over of the former and it causes issues. Most find that a purge of the installed version and then install of the new version again repairs this. Your settings and guests will remain, but I always suggest a good backup is never out of order.
