When i'm trying to start my VM in Vbox i got this error

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please try setting it up again by executing


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.

My secure boot is disabled, and i followed solution here. At 5- Add exec permission and run the script when i type chmod 700 sign-virtual-box then after i type ./sign-virtual-box now, idk how to fix this:

modinfo: ERROR: Module vboxdrv not found.
dirname: missing operand
Try 'dirname --help' for more information.
