And this is why I avoid and will always avoid "Secure Boot". I can see many newer Linux people being locked out starting in Sept.
Or you could just remove microsoft's keys from your systems and sign your bootloader with your own key. That's what I do on all of my systems so I am unimpacted by this.
Sure, but that's a lot more work than just disabling Secure Boot, and for most people's threat models, there's zero actual security benefit gained in return.
