How to remove CentOS Secure Boot CA Key?

Post by jack.lan » 2018/12/12 10:27:41

Hi everyone

We want to boot only kernel sign myself key with secure boot, so we want to remove CentOS Secure Boot (CA Key 1) and Red hat Key with mokutil tool.

with mokutil --reset and reboot enter Perform MOK management blue screen.

select "Reset MOK" item key in password.

screen will show ERROR "Failed to set variable: (0xE) Not Found" .

but we can display CentOS Secure Boot (CA Key 1) with "mokutil --list-enrolled" command.

what happen?

Are these two keys built into os?

Can anyone give me some advice?
