Update Secure Boot page: AlmaLinux 8 shim 16.1 is dual-signed#810
Merged
Conversation
AlmaLinux 8 now ships shim-16.1-2.el8.alma.1: x86_64 binaries are dual-signed with the Microsoft 2011 and 2023 UEFI CAs, aarch64 is signed with the 2023 CA only — same as AlmaLinux 9 and 10, following RHEL. Simplify the status section accordingly and note that fwupd on AlmaLinux 8 (1.7.8) cannot deliver the db/KEK certificate updates.

- Use fwupdmgr --version | grep fwupd (works on AlmaLinux 8 too) and state the expected minimum/current versions - Scope the fwupd step title to AlmaLinux 9 and later - Point AlmaLinux 8 users to the alternative enrollment from the fwupd note - Mention older AlmaLinux/fwupd releases in the manual enrollment intro
