virtualbox 6.1.14 on Ubuntu 20.04 (5.4.0-48-generic)

[prabh]

Hi, Please can you help me install VirtualBox 6.1.14 on Ubuntu 20.04 (5.4.0-48-generic) I am getting following errors during installation. ###### udo /sbin/vboxconfig vboxdrv.sh: Stopping VirtualBox services. vboxdrv.sh: Starting VirtualBox services. vboxdrv.sh: Building VirtualBox kernel modules. vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.

There were problems setting up VirtualBox. To re-start the set-up process, run

/sbin/vboxconfig

as root. If your system is using EFI Secure Boot you may 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. ####### dmesg here

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

'/sbin/vboxconfig'

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.
