VirtualBox virtual image won't start. Says something about a key. What's the matter?

Question

linux

I'm trying to run a virtual image of Ubuntu Server on VirtualBox. The launch fails and the following message is displayed:

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall virtualbox-dkms package and load the kernel module by executing

'modprobe vboxdrv'

as root.

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

Climbed the entire Internet, reinstalled everything that is possible. The only point that suggests the reason is that when I try to enter a command,
sudo modprobe vboxdrv
I get the following message:

\modprobe: ERROR: could not insert 'vboxdrv': Required key not available

What's the matter? What key are you talking about? How to fix it?
