Comment 0 for bug 1533258

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. References

2.1 Output of

 dpkg --list | grep grub

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

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

sudo dpkg -i *.deb
