SecureBootKey

In order to use ELRepo's kernel modules (kmod packages) on a system with Secure Boot enabled, system administrators must import the ELRepo Secure Boot public key into their Machine Owner Key (MOK) list. This page explains how this is done. Please note that ELRepo's kernel packages (kernel-ml and kernel-lt) are not signed with the Secure Boot key.

If you have installed the elrepo-release package as shown on our HomePage, the secureboot key will be found as /etc/pki/elrepo/SECURE-BOOT-KEY-elrepo.org.der . Or you can download it directly from our site:
