New user - problem starting in VirtualBox

Installation
1

Hello

I’m new to HomeAssistant. I try to install it on a Linux Ubuntu laptop with VirtualBox
I installed VirtualBox and configured a new vm as described on the documentation page:

when starting the virtual machine, I receive an error screen:

*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.*

WHen starting from the command line, I see this:

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

I installed virtualbox-dkms package and linux-headers-generic package
When I try to execute the command “sudo modprobe vboxdrv” I receive a

"modprobe: ERROR: could not insert 'vboxdrv': Operation not permitted
"

can you suggest a solution?
thank you
Vincent

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

ok, modprobe problem seem to be solved.
I followed instructions from https://askubuntu.com/questions/920689/how-to-fix-modprobe-vboxdrv-error-in-virtualbox

I had a new error in VirtualBox when starting the vm:


Échec de l'ouverture de session pour la machine virtuelle **HomeAssistant**.

VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED).

|Code d'erreur :|NS_ERROR_FAILURE (0x80004005)|
| --- | --- |
|Composant :|ConsoleWrap|
|Interface :|IConsole {872da645-4a9b-1727-bee2-5585105b9eed}|

=> this required to activate the virtualisation option in the Bios

problem solved so far!
