This "repair disk" is developed with zero coordination with the Ubuntu developers and the resulting changes to the disk are unsupportable by us. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1528345 Title: grub or kernel update broke Secure Boot by putting grubx64.efi instead of shimx64.efi in EFI boot order Status in One Hundred Papercuts: Confirmed Status in grub2 package in Ubuntu: Triaged Status in linux package in Ubuntu: Invalid Bug description: I've been running Ubuntu on a Lenovo ThinkPad X240. I initially installed 14.10 when I got the machine in January. I then upgraded to 15.04, and on Monday evening (late December 14) I upgraded to 15.10. I rebooted once right after the update to make sure some postfix and opendkim configuration changes I made worked correctly after rebooting. Then between Monday evening and Friday evening (December 19) there were a bunch of system updates that I installed. On Friday evening I decided to reboot to boot into the updated kernel. (There were also grub updates in that interval.) When I rebooted, the laptop said: Secure Boot Image failed to verify with *ACCESS DENIED* Press any key to continue. See the image (posted by somebody else) of this error in http://askubuntu.com/questions/710146/how-to-fix-secure-boot-error- image-failed-to-verify-with-access-denied-on-st I had to disable secure boot to make the system boot. Based on the discussion in http://askubuntu.com/questions/710146/how-to-fix-secure-boot-error-image-failed-to-verify-with-access-denied-on-st it appears that the problem is that the updates caused it to try to boot directly to grub (File(\EFI\ubuntu\grubx64.efi)) rather than via the shim (File(\EFI\ubuntu\shimx64.efi)). I don't know for sure what sequence of events caused that, nor did I verify for certain that it was booting via the shim before. However, I know that this reboot on Friday was the first time I had a secure boot failure since installing Ubuntu on the laptop (and using only Ubuntu; no other OSes involved) in January. I'll attach a list of the system updates that were applied in the interval between the successful boot and the failed one from /var/log/dpkg.log . Note that the log is in UTC but my description above ("evening", etc., is in UTC-8, so the evening of December 14 is actually around 07:00 UTC on December 15). Note that this log contains a grub update, two kernel updates, and the removal of the first of those kernel updates via apt-get autoremove.
