Secure boot for slowroll SSD

I installed slowroll on a laptop with self-upgraded SSD. The laptop needed servicing, so I sent it back with the factory SSD, and it has been returned to me with the BIOS reset.

How do I configure Secure Boot to boot from my already setup SSD? It currently will not boot due to secure boot, and from what I can glean from web searches, openSUSE should support secure boot, but I am not sure how to setup.

Start by downloading the live Tumbleweed media. You should be able to boot that with secure-boot on.

Then you did something wrong during installation or you misinterpret what you see. openSUSE is by default installed with Secure Boot support.

It just happens during installation. As you did not provide any information about the error(s) you see it is impossible to even guess why it does not work.

Start with showing a photo of the error you get during boot.

The BIOS says

Secure Boot Violation
Invalid signature detected. Check Secure Boot Policy in Setup.

I installed slowroll. Any installation changes to the BIOS secure boot key storage (not sure of the exact term) has been erased as the laptop has been restored to factory settings. My SSD still has the openSUSE installation on it, as I swapped out the factory SSD to put the openSUSE one back upon receiving it back. Do I still need the Tumbleweed installation media to be able to boot my existing drive?

With the Agama installer, I have tried booting with starting with BIOS boot options:
USB HDD
USB FDD
USB CD

All give me the same secure boot violation message.

Also, openSUSE boots fine with secure boot disabled. So the problem is definitely secure boot.

Maybe you need redo the signatures, maybe something like this: Restore Secureboot Signatures

Your post is barely readable. Always use preformatted text for computer output. You see how I post computer commands, do not you?

Anyway - it all looks good. Sounds like you do not have the expected certificate(s) in your BIOS. Show

mokutil --db
sbverify --list /boot/efi/EFI/opensuse/shim.efi

You probably need to install sbsigntools first.

I guess you prefer side -scrolling?

As you see you do not have keys used by Microsoft to sign (third-party) shim. This really looks like Windows-only. Quoting Microsoft (emphasis mine)

You may try resetting Secure Boot keys to default in BIOS setup (if this option is not available, you may try resetting complete BIOS to default). If that still fails, this is the question to the vendor of your system. In principle, it may be possible to enroll your own PK and KEK to enable db update and then enroll Microsoft keys (including additional Microsoft KEK to allow automatic updates). But it still may cause firmware updates to fail.

I stay corrected. Your firmware does include the new Microsoft third party certificate “Windows UEFI CA 2023” which will phase out the old certificate “Microsoft Corporation UEFI CA 2011” that expires in year 2026. The problem is that currently openSUSE shim is still signed by the old certificate and for this reason rejected on your system.

It is unclear whether future shim binaries will be signed by both certificates.
