Oracle VirtualBox Kernel Driver not installed (rc=-1908)

[btforensics]

Hello Debianuserforums,

I currently installed Oracle Virtual box to my Debian "Stretch" Machine (Cinnamon).

Initially I followed the instructions from the link below to install Oracle Virtual Box 5.1
https://backports.debian.org/Instructions/

I plan to install another Debian as a guest VDI image in Oracle Virtual Box. Followed the on screen instructions in creating the image in Oracle Virtual Box.

However, when I try to boot the image to proceed with the installation, I keep on getting this error:

Oracle VirtualBox 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 executed vboxconfig, encountered a message that "modprobe vboxdrv failed…"

I uninstalled Oracle VirtualBox 5.1 and installed 5.2 but I keep on getting the same error.

I ran the dmesg command and got the following message:
vboxdrv: disagrees about version of symbol cpu_tlbstate
vboxdrv: Unkown symbol cpu_tlbstate (err-22)

I've tried multiple solutions I've found from the internet but none is working.

Thank you for your help!

I don't know enough about virtualbox to be of much assistance, however this error message may provide some more clues.

vboxdrv: disagrees about version of symbol cpu_tlbstate
vboxdrv: Unkown symbol cpu_tlbstate (err-22)

If you can load the kernel module directly and then list all modules, it should give some more verbose output, which you are free to post up here.

After researching, I found this article
https://forum.manjaro.org/t/solved-virt ... date/24875

It says to do the following
sudo pacman -Sy virtualbox virtualbox-host-dkms
sudo pacman -R linux44-virtualbox-host-modules

Now I'm having issue with pacman, did more troubleshooting and successfully installed pacman, but now I'm getting this error when running pacman
warning: no 'XferCommand' configured
error: no usable package repositories configured

It seems that everytime I try to fix something I will encounter new issues. Maybe I need to install the other Debian packages
debian-9.4.0-amd64-DVD-2.iso
debian-9.4.0-amd64-DVD-3.iso

Can anyone tell me how to install these packages?

Thank you

After doing research, I was now able to resolve the issue.

I executed the following commands:
apt-get update && apt-get upgrade && apt-get dist-upgrade

Restarted, and the issue has been solved!

Thank you!
