Hello. I'm using Ubuntu 24.04 right now,but what I'm trying to do is to virtualize Debian 12 as a vm using qemu + kvm + virt-manager and I want to passthru my gpu from Ubuntu to Debian. And infact this is what I did. Debian is running now,but I'm facing a problem with the nvidia driver. This is how I have installed it :
1. added to /etc/apt/sources.list these repos : deb http://deb.debian.org/debian/ bookworm contrib main non-free non-free-firmware deb-src http://deb.debian.org/debian/ bookworm main non-free-firmware deb http://deb.debian.org/debian/ bookworm-updates contrib main non-free non-free-firmware deb-src http://deb.debian.org/debian/ bookworm-updates contrib main non-free non-free-firmware deb http://deb.debian.org/debian/ bookworm-proposed-updates main non-free non-free-firmware deb-src http://deb.debian.org/debian/ bookworm-proposed-updates main non-free non-free-firmware deb http://deb.debian.org/debian/ bookworm-backports contrib main non-free non-free-firmware deb-src http://deb.debian.org/debian/ bookworm-backports contrib main non-free non-free-firmware deb http://security.debian.org/debian-security bookworm-security main non-free non-free-firmware deb-src http://security.debian.org/debian-security bookworm-security main non-free non-free-firmware and then : 2) # apt install nvidia-detect nvidia-driver Let's give a look at what happened when I have modprobed the nvidia driver : root@mario-Standard-PC:/home/marietto# sudo modprobe nvidia modprobe: ERROR: could not insert 'nvidia_current': Key was rejected by service modprobe: ERROR: ../libkmod/libkmod-module.c:1047 command_do() Error running install command 'modprobe -i nvidia-current ' for module nvidia: retcode 1 modprobe: ERROR: could not insert 'nvidia': Invalid argument Loading of module with unavailable key is rejected I've googled a little bit to find a solution and I read that I should use the script sign-file to sign the nvidia driver,but it didn't work : /usr/lib/linux-kbuild-6.1/scripts/sign-file sha512 /var/lib/shim-signed/mok/MOK.priv /var/lib/shim-signed/mok/MOK.der /lib/modules/5.19.0-23-generic/updates/dkms/nvidia.ko At main.c:298: - SSL error:FFFFFFFF80000002:system library::No such file or directory: ../crypto/bio/bss_file.c:67 - SSL error:10000080:BIO routines::no such file: ../crypto/bio/bss_file.c:75 sign-file: /lib/modules/5.19.0-23-generic/updates/dkms/nvidia.ko it seems that I'm not able to sign the driver because the presence of some bugs ? This is too much technical for me at this pont to be able to find a fix for this ugly bug and I'm asking some help. -- Mario.
