Hi Anil The instuctions you are following seem incomplete. I do not use nvidia myself but according to https://dev.to/dev-charodeyka/debian-secure-boot-to-be-or-not-to-be-that-is-the-question-1o82 then you need to create the MOK first. The example given on that page is the following: $ su - #if you are logged # mkdir -p /var/lib/shim-signed/mok/ # cd /var/lib/shim-signed/mok/ # openssl req -nodes -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -days 36500 -subj "/CN=My Name/" # openssl x509 -inform der -in MOK.der -out MOK.pem After that you can import they new MOK $ sudo mokutil --import /var/lib/shim-signed/mok/MOK.der # prompts for one-time password sudo reboot After the reboot there should be some kind of MOK import prompt you need to go through to accept your new MOK.
