Hi,
I'm trying to install VB in Debian 9 and, as I tried to open my first VM, I get this error message:

"Kernel driver not installed (rc=-1908)

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 followed their advice and executed "/sbin/vboxconfig', which generated its own error message:

"Created symlink /etc/systemd/system/multi-user.target.wants/vboxdrv.service → /lib/systemd/system/vboxdrv.service.

I downloaded and installed the packages they referred on the message, but it didn't change anything.
If anyone could help, it would be greatly appreciated.
Thank you

Which parts exactly? The headers? The build tools? All of them? None of them? It would be better if you included the error after you took corrective action, not before.

The error message is the same before and after corrective measures, and I installed just the headers.

Then the corrective action was not... correct
If you had installed the appropriate headers and tools, you wouldn't be having that error. Please try again...
