Hi all,
I have virtualbox installed in Fedora 39, and I’m trying hard to sign the virtualbox modules, which is a requirement if secure boot is enabled. I checked a stackoverflow response to do this.
It has 2 steps: add the key using mokutil, and sign the modules.
I have completed the first part (enrolled the MOK.der file, rebooted the system and entered the passphrase to enroll the key). But I couldn’t sign the modules.
The stackoverflow response that I followed:
The code enclosed within the response:
#!/bin/bash
# Store the module directory in a variable
module_dir=$(dirname $(modinfo -n vboxdrv))
# Iterate over the module files directly
for modfile in "$module_dir"/*.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
I am using Fedora 39 with Linux Kernel 6.5 (Linux 6.5.12-300.fc39.x86_64 #1 SMP PREEMPT_DYNAMIC Mon Nov 20 22:44:24 UTC 2023 x86_64 GNU/Linux)
Could someone help me with signing the modules?
