virtualbox will not start after upgrade of chromeos

[1na]

Hi after an upgrade of Chromeos, I cannot set up virtual box. Please help.

I am on

 v 53.0.2785.103 (64-bit) on Platform 8530.81.0 
(Official Build) stable-channel panther 
Firmware Google_Panther.4920.24.26

I have rerun sudo sh ~/Downloads/change-kernel-flags and setup-headers.sh.

There was an error for a bad header, but otherwise the output was fine, see below

# This script will add the repo to your sources, download
and install the kernel headers appropriate to your
kernel version and architecture.

If you made any changes to rc.local, then you should reapply them in the new
/etc/rc.local. Your old file is named /etc/rc.local.old.

All done now, you can install virtualbox. Note that you need to log out of your chroot
and start it again to load the modules needed for virtualbox.
======================================================================================

However when I want to start the chroot I get this warning

WARNING: The vboxdrv kernel module is not loaded. Either there is no module
         available for the current kernel (3.8.11) 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 indeed no virtual machines will start.

Rerunning the script as suggested gives

vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.

Now I am stuck. I do not know what to look for in dmesg and I do not know why vboxdrv failed to load.

Any help appreciated.

[mwhipple]

The relevant output in dmesg would likely start with vboxdrv, would be near the end, and would be repeated one time for each failed invocation.

It looks like you're hitting this: #40 so integrating #46 may help you past your immediate issue.

Thanks I will try that and post the result here.

The custom repos are failing to update:

Failed to fetch https://raw.githubusercontent.com/divx118/crouton-packages/master/dists/3.8.11/main/binary-amd64/Packages Bad header line

I'm not familiar with the script, but I assume this is where the compiled .deb image and header files are coming from. You'll need to either find a copy of these files appropriate for your setup. Probably here: divx118/crouton-packages/tree/master/dists/3.8.11

Or probably better, compile from source. Instructions here: dnschneid/crouton/wiki/Build-kernel-headers-and-install-Virtualbox-(x86)
