Ok, thanks for the clarification. I overlooked that this problem started affecting you two months ago, I didn't expect a bug report would be based on a boot problem from so long ago.
A few things: - your file timestamps date back to May. Can you attach the apt term log for *this* period? (which should be /var/log/apt/term.log.3.gz) - you reported this bug against shim 0.8-0ubuntu2, however the files listed in your /boot/efi/EFI/ubuntu directory do not match this version. Do you have the shim-signed package installed at all? - your grubx64.efi looks too small to be the one from grub-efi-amd64-signed, by a factor of 4. Do you have grub-efi-amd64-signed installed? - if 'efibootmgr -v' returns no results, this means Ubuntu is unable to detect any configured EFI boot options on your system. Did you change your system to boot in BIOS mode, and not just disable secureboot? Since you report this against shim version 0.8-0ubuntu2, which has not yet been released as an SRU to trusty-updates, this means that you have trusty-proposed enabled and have installed shim from there. There's a good chance that you did this at a time that no corresponding version of shim-signed was available in trusty-proposed, causing this package to be removed from your system. Running systems with -proposed enabled is not generally recommended for end users, and this kind of package removal is an unavoidable consequence of doing so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1489987 Title: Secure Boot failed on Ubuntu 14.04 on Dell E7440 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1489987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
