Sign virtual box modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) Centos 8 [closed]

After some research, I found the solution.

Solution 1 : disable secure boot.

Solution 2 :

1- Install mokutil package

sudo dnf updatesudo dnf install mokutil

2- Create RSA key under new folder.

sudo -imkdir /root/signed-modulescd /root/signed-modulesopenssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=VirtualBox/"chmod 600 MOK.priv

3- This command will ask you to add a password, you need this password after the next reboot.

sudo mokutil --import MOK.der

4- Reboot your system and a blue screen appear, select Enroll MOK --> Continue --> put the previous password and your system will start.

5- Put the previous cmmands in a script to run it later (after system update)

cd /root/signed-modulesvi sign-virtual-box

Add the following cmd to this script :

#!/bin/bashfor modfile in $(dirname $(modinfo -n vboxdrv))/*.ko; do  echo "Signing $modfile"  /usr/src/kernels/$(uname -r)/scripts/sign-file sha256 \                                /root/signed-modules/MOK.priv \                                /root/signed-modules/MOK.der "$modfile"done

Use the below to find signfile if the above fails & edit script accordingly.

find /usr/src -name signfile

5- Add exec permission and run the script

chmod 700 sign-virtual-box./sign-virtual-box 

6- Launch VirtualBOx

modprobe vboxdrv

I follow the solution given by @Younes LAB but I needed to change the sign-file path in the sign-virtual-box script for it work fine:

#!/bin/bashfor modfile in $(dirname $(modinfo -n vboxdrv))/*.ko; do  echo "Signing $modfile"  /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256 \                                /root/signed-modules/MOK.priv \                                /root/signed-modules/MOK.der "$modfile"done

I am using Ubuntu 20.04.2 LTS and VirtualBox 6.1

I upgraded from virtualbox 6.0 to 6.1 and vboxconfig ran without an error (or the need to sign kernel modules).
