Suddenly incompatible. Maybe new VirtualBox in Ubuntu?

[interstar]

I installed Vagrant and VirtualBox on my Ubuntu 11.10 machine a few
weeks ago, and have been very happy with it.

Suddenly yesterday I started getting this message when trying to
vagrant up :

"
Vagrant has detected that you have a version of VirtualBox installed
that is not supported. Please install one of the supported versions
listed below to use Vagrant:

4.0, 4.1
"

I'm guessing that maybe Ubuntu upgraded my VirtualBox - it seems to be
4.1.2_Ubuntu - and Vagrant no longer knows what to do with it.

Does that sound plausible?

And is this a real incompatibility? Or could vagrant work fine with
4.1.2_Ubuntu but doesn't recognise the number? Is there a fix?

cheers

Phil,

Two things to try:

1. Run VBoxManage --version and see if VirtualBox is actually giving
you some error case.

2. Run with VAGRANT_LOG=debug to see what is going on.

Hi Mitchell,

thanks for the reply. When I run VBoxManage --version

I see this.

WARNING: The character device /dev/vboxdrv does not exist.
Please install the virtualbox-ose-dkms package and the appropriate
headers, most likely linux-headers-generic.

You will not be able to start VMs until this problem is fixed.
4.1.2_Ubuntur38459

I did install the virtualbox-ose-dkms package and that hasn't fixed
the problem. ( linux-headers-generic was already installed )

Should I infer from this that the problem isn't with vagrant? That
vagrant is just bailing (with a misleading error message) because its
attempt to start virtualbox is failing?

I set an environment variable called VAGRANT_LOG to equal debug and
ran vagrant up again. No difference in error message it gives. Are
there error logs somewhere? (Can't see any in /var/log/ and this post
http://groups.google.com/group/vagrant-up/browse_thread/thread/3f65a3ef947ddb46
suggests that there may not be.)

cheers

Phil

OK. So I did some stuff from here : http://askubuntu.com/questions/71441/virtualbox-ubuntu-11-10-linux-kernel-3-cannot-start-virtual-machine

And it seems to be working. Though not sure if  it was the kernel thing or the connect to virtualbox.org thing that did it.
