I am getting this error when I am trying to install VirtualBox-6.1. I cannot turn off the secure boot. I am installing Virtual box for I want to use Homestead

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.

  • If you're using focal (20.04), why are you trying to install a package built for eoan (19.10). Problems should be expected? Why not us the focal (20.04) intended package from the repositories? (vvirtualbox | 6.1.6-dfsg-1 | focal/multiverse | source, amd64) – guiverc Mar 15 '21 at 11:42
  • I have downloaded the package from Virtual Box for Ubuntu 19.10 / 20.04 – Subhasish Gupta Mar 16 '21 at 11:37

Maybe a Kernel issue, First install mainline here

Then downgrade the kernel to 5.4 by: installing it edit sudo vim /etc/default/grub as follow

GRUB_DEFAULT="**gnulinux-5.4.112-0504112-generic-advanced-06ee5ff5-b952-4d40-858f-869172f710ce**"

GRUB_TIMEOUT_STYLE=hidden GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=""

Update grub sudo update-grub then sudo reboot After reboot sudo apt remove virtualbox-dkms and then sudo apt install virtualbox-dkms to rebuild for the 5.4 kernel

then sudo modprobe vboxdrv

done!
