[Bug 1385690] Re: Secure Boot Violation

[blazerw]

I had the same issue when upgrading from 14.04 to 14.10. I went into the
bios to look at secure boot settings and it had a setting for default
boot image. There were two listed "ubuntu" and "Ubuntu". When I switched
the default from "ubuntu" to "Ubuntu" the message went away and computer
boots with no problem.

It seems to me that 14.10 is using "Ubuntu" for the image name while
14.04 was using "ubuntu". So, instead of replacing the existing signed
boot image, 14.10 makes a new one that is not the default. The old one
still boots the system, but causes the error.

I am not a kernel developer, so this is just a guess based on what I
saw.
