Kernel upgrade on Rocky 8 reports a signature issue.

You will need to disable secure boot or read [this page](https://elrepo.org/wiki/doku.php?id=secureboot&s%5B%5D=secure&s%5B%5D=boot).

Sounds like “read this page” is the correct solution.

elrepo’s kernels are not SB-aware. You need to disable SB to install them.

The page says

> 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

So I don’t understand.

That is “kernel modules” (for RHEL kernels).  
The kernel by ELRepo is a different thing.

After using `mokutil --import /etc/pki/elrepo/SECURE-BOOT-KEY-elrepo.org.der` to sign, the invalid kernel signature issue still persists.

You will need to disable secure boot, then. A maintainer in a previous reply in this thread has stated the kernels are not secure boot aware.
