"We don't have that kind of relationship with Microsoft. The only public key that every UEFI firmware is guaranteed to have is Microsoft's, and only Microsoft owns the private key."
An hour ago:
This is how to sabotage GNU/Linux distros that Microsoft does not control.
"Looks like I will not be installing POP OS again, still require Secure Boot to be disabled."
What's wrong with that?
See, now we're meant to think that distros need to constantly ask Microsoft for permission to merely boot on hardware. Even hardware that's in no way connected to Microsoft but defaults to restricted boot (sometimes making it exceedingly hard to turn off).
For me pointing this out for 13+ years all I got was SLAPPs. █
