I was using VirtualBox (installed from Ubuntu repositories) on the day right before I installed the most recent upgrade for Ubuntu 22.04.2 LTS which installed Linux kernel 6.1.0-1015, previous kernel was 5.15.0-76. Since then I can not start VirtualBox. What can I do? It shows this error:

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please reinstall virtualbox-dkms package and load the kernel module by executing

'modprobe vboxdrv'

as root.

If your system has EFI Secure Boot enabled you may also need to sign the kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load them. Please see your Linux system's documentation for more information.

where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

The recommended solution fails:

When trying to reinstall virtualbox-dkms, I can see the problem here:

Loading new virtualbox-6.1.38 DKMS files...
Building for 6.1.0-1015-oem
Module build for kernel 6.1.0-1015-oem was skipped since the
kernel headers for this kernel does not seem to be installed.

Found a solution here, regarding a similar problem with Nvidia drivers not working after kernel update:

sudo dkms autoinstall

And reboot, now it's working again.


For ref in case anyone else looking for a solution, I don't have nvidia drivers but running

sudo apt install dkms

installed what was needed and then (again)

sudo dpkg -i virtualbox-7.0_7.0.14-161095~Ubuntu~jammy_amd64.deb

worked for me on 22.04.
