[Bug 1747889] Re: System not booting after update

[Katharina Zwinger]

Thank you for you detailed answer!

The system firmware seems to be a bit buggy, I wouldn't be surprised if
it's actually a firmware bug. I just don't quite understand yet, how the
firmware bug was triggered by the OS update… and why this couldn't be
solved by restoring secure boot to factory default?

The weird thing is, I've been using this notebook for more than a year
now with Ubuntu 16.10, 17.04 and 17.10, no dual boot, and never had any
trouble booting after I've added the shimx64.efi to trusted files on the
very first install. Also, I've never touched boot settings anywhere
except for the F2 menu on startup.

Here is the output of 'efibootmgr -v':

Title:
  System not booting after update

Status in shim-signed package in Ubuntu:
  Confirmed

Bug description:
  After installing the latest updates for Ubuntu 17.10, my computer
  (Acer Aspire V3-372) was no longer able to boot. It got stuck in a
  loop, displaying the following error message for a few milliseconds,
  then restarting again:

  System BootOrder not found. Initializing defaults.
  Creating boot entry "BootXXXX" with label "ubuntu" for file "\EFI\ubuntu\shimx64.efi"

  I suspect this has something to do with the update to shim-signed
  1.33.1~17.10.1 as "Failure to boot or validate validly signed EFI
  binaries" is listed as a potential regression on
  https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1708245/+editstatus

  There was also a very similar bug reported for Fedora 27:
  https://bugzilla.redhat.com/show_bug.cgi?id=1512410

  Selecting any (new) UEFI files as trusted did not solve the issue,
  neither did disabling secure boot or resetting the secure boot option
  in BIOS to factory default and it's still not working after adding
  EFI/ubuntu/shimx64.efi to trusted files again.

  The workaround I've found for now, is selecting "EFI File Boot 0"
  (which is the previously added trusted file) as primary boot device.
  But that's just a workaround, I think I should be able to just boot
  from my SSD as before.
