Selecting grub entries (efi) at boot time leads to "error: symbol 'grub_efi_find_last_device_path' not found"

[Michael Frericks]

1. Situation

1.1 I installed Ubuntu 14.04 on an OEM "Windows 8.1" laptop more than a year ago
1.2 Ubuntu installed grub to manage OS selection
1.2 The last automatic software update of Ubuntu (09.01.2016) updated grub (see https://bugs.launchpad.net/ubuntu/+source/grub2/2.02~beta2-9ubuntu1.7)
1.3 Since then selecting grub menu items to start windows produces the following error message

    "symbol 'grub_efi_find_last_device_path' not found"

1.4 Reverting back to https://bugs.launchpad.net/ubuntu/+source/grub2/2.02~beta2-9ubuntu1.6 solves this issue
1.5 Retrying to upgrade from 2.02~beta2-9ubuntu1.6 to 2.02~beta2-9ubuntu1.7 reintrocudes the issue

2.4 Reverting to grub 2.02-beta2-9ubuntu1.6_amd64

You can start synaptic "sudo synaptic" and force the previous version of these packages (Package->Force version...) and lock that version (Package->Lock version...).

I did it manually as described below:

Steps:

1. Download the following files (from https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/8443424) in a separate (newly created) folder

grub2-common_2.02~beta2-9ubuntu1.6_amd64.deb
grub-common_2.02~beta2-9ubuntu1.6_amd64.deb
grub-efi-amd64_2.02~beta2-9ubuntu1.6_amd64.deb
grub-efi-amd64-bin_2.02~beta2-9ubuntu1.6_amd64.deb
grub-efi_2.02~beta2-9ubuntu1.6_amd64.deb

2. From that folder install the deb files with the following command:

sudo dpkg -i *.deb

Status changed to 'Confirmed' because the bug affects multiple users.

[Glenn Goldie (ggoldie)]

Would like to confirm this bug, I recently experienced the exact same error when trying to boot a Windows8.1 install from grub menu. My Linux Mint 17 continued to boot normally.

I attempted to remove/reinstall grub with all defaults etc.. no change.

I found in my update history updates of 6 x grub packages firstly from 1.3 to 1.6 and then from 1.6 to 1.7 on January 6th.

grub2-common
grub-common
grub-efi
grub-efi-amd64
grub-efi-amd64-bin
grub-pc-bin

I rolled back to 1.3 using files in /var/apt/cache/archives and presto, Windows boots just fine again. Updated to 1.6 and Windows still boots. Updated to 1.7 and it breaks again with exact same error as reported in this bug.

[Graham (gramorey)]

Another confirmation, and have been waiting for a fix for some time now. Winding back is not a fix. Please assign someone to this.

It might appear that MS are not the only ones to arrogantly ignore the possibility of coexisting OSs.

[Luis Sieira García (jaimito-hendrix)]

@carolin-wildt, I'm experiencing the same issue, If you need any help, or testers, or whatever, don't hesitate to ask

[Carolin Wildt (carolin-wildt)]

@Luis Siera Garcia, yes I have the same problem with windows 7and no solution until now...

Carolin, please try running sudo efibootmgr -o 0002,0001, reboot, and see if that fixes it. Also run sudo efibootmgr -v after the reboot again.

Could both of you also run md5sum on /boot/efi/EFI/Microsoft/Boot/bootx64.efi? And have you both used boot repair in the past to get the system booting?

boot repair i already tried

[Carolin Wildt (carolin-wildt)]

how can I test if md5sum on /boot/efi/EFI/Microsoft/Boot/bootx64.efi runs?

[Phillip Susi (psusi)]

What? That didn't make sense. Can you go into your bios and try to change the boot order there? It looks like it is buggy and refuses to accept the boot configuration and will only boot the hard drive like it is a removable media. You might try deleting the Boot directory on your EFI system partition and see if that helps ( but keep a copy of it somewhere else so you can put it back if the system becomes unbootable ). Otherwise, the only thing for it is to copy ubuntu/grubx64.efi to Boot/bootx64.efi and complain to the manufacturer about their broken firmware ( or better yet, return it for a refund and buy from someone who doesn't use broken firmware ). This is what boot-repair did when you used it before, and after updating grub, the copy is now out of date, hence the error.

[Carolin Wildt (carolin-wildt)]

Sorry, I don't know very good how to make all this stuff- I don't understand half of it. If there are some simple things like copy and paste something to terminal- I'll make it ;)
Is there any possibility to return to old grub version....?

[Michael Frericks (michael-frericks)]

@carolin wildt

see in the report above at section 2.4 to revert back:

2.4 Reverting to grub 2.02-beta2-9ubuntu1.6_amd64

Steps:

1. Download the following files in a separate (newly created) folder

grub2-common_2.02-beta2-9ubuntu1.6_amd64.deb
grub-common_2.02-beta2-9ubuntu1.6_amd64.deb
grub-efi-amd64_2.02-beta2-9ubuntu1.6_amd64.deb
grub-efi-amd64-bin_2.02-beta2-9ubuntu1.6_amd64.deb
grub-efi_2.02-beta2-9ubuntu1.6_amd64.deb

[Carolin Wildt (carolin-wildt)]

@Michael Frericks: Is there any link, where to download? Can't find all of them...

[Luis Sieira García (jaimito-hendrix)]

@Carolin Wildt

The packages are still in the repositories, you can downgrade via apt-get

sudo apt-get install grub2-common=2.02~beta2-29ubuntu0.2 \
  grub-common=2.02~beta2-29ubuntu0.2 grub-efi-amd64=2.02~beta2-29ubuntu0.2 \
  grub-efi-amd64-bin=2.02~beta2-29ubuntu0.2

sudo apt-mark hold grub-common grub-efi-amd64-bin grub2-common grub-efi-amd64

The hold line will avoid future updates, so you will have to "unhold" the packages as soon as the bus is closed

[Carolin Wildt (carolin-wildt)]

@Luis Sieira: Thanks. But it's still not working. I don't know why...

[Phillip Susi (psusi)]

You don't need to downgrade, you just need to copy ubuntu/grubx64.efi to Boot/bootx64.efi, which is what boot-repair did before. You can either run it again or manually copy the file.

[Michael Frericks (michael-frericks)]

How can this be a duplicate of the 2 years old bug #1366546?

This one here occured recently (~ January 2016)

The preveios version of grub2-common_2.02 - i my case grub2-common_2.02-beta2-9ubuntu1.6_amd64.deb - works fine.

The questions is: What has changed from

     grub2-common_2.02-beta2-9ubuntu1.6_amd64.deb

to

    grub2-common_2.02-beta2-9ubuntu1.7_amd64.de

[Phillip Susi (psusi)]

Because it occurs every time grub is updated when you have a broken system that only works because boot-repair made a copy of the main grub image. When grub is then updated, your system is still trying to use the old main image, but with the new modules.

[Carolin Wildt (carolin-wildt)]

@Luis: You wrote me this: The packages are still in the repositories, you can downgrade via apt-
get

sudo apt-get install grub2-common=2.02~beta2-29ubuntu0.2 \
  grub-common=2.02~beta2-29ubuntu0.2 grub-efi-amd64=2.02~beta2-29ubuntu0.2 \
  grub-efi-amd64-bin=2.02~beta2-29ubuntu0.2

sudo apt-mark hold grub-common grub-efi-amd64-bin grub2-common grub-efi-amd64

has anyone resolved this? bug #1366546 does not seem to be moving

this was proposed by psusi:
cd /boot/efi/EFI
sudo cp ubuntu/grubx64.efi Boot/bootx64.efi
is this safe?

another option was to downgrade to grub 2.02-beta2-9ubuntu1.6_amd64

[poppis (poppis-poikela)]

for me, copying ubuntu/grubx64.efi did not solve the issue, instead downgrade to 2.02-beta2-9ubuntu1.6 solved it.

This bug has nothing to do with bug 1366546, so I've deduplicated it. This is a bug in boot-repair or whatever has created the boot images being used, as Phillip pointed out.

[Mathieu Trudel-Lapierre (cyphermox)]

It's not an issue in grub -- grub simply installs the bootloader in EFI/ubuntu, not in EFI/boot. I don't know what happened to get the system in this state; but to fix this we'll first need to know the current state of boot variables -- could you please paste in the output of the following command:

efibootmgr -v

Am having the same issue (dual boot, win10 and linux mint based on ubuntu 14.04).
Linux boots, but not win10.

Looks like bug was introduced with 2.02~beta2-9ubuntu1.7.diff.gz

Check here for the commit details:
http://launchpadlibrarian.net/230268356/grub2_2.02~beta2-9ubuntu1.6_2.02~beta2-9ubuntu1.7.diff.gz

Maybe the author of the affected 1.7 version (dann frazier) can help us - I added his e-mail to the subscriber list of this bug.

My details:

By the way, old version of grub (1.6 version) can be also downloaded here:
