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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1385690 Title: Secure Boot Violation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1385690/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
