Bug#905570: fwupd: Firmware update failed on Lenovo P50

[Sam Morris <sam@robots.org.uk>]

Package: fwupd
Version: 1.1.0-7
Severity: normal

I noticed the following update available for my Lenovo P50:

20EQA063UK System Firmware has firmware updates:

Update Description:      CHANGES IN THIS RELEASE Version 1.52
                         
                         [Important updates] Nothing.
                         
                         [New functions or enhancements] - Updated the Diagnostics module to version 04.00.001.
                         
                         [Problem fixes] - Fixed an issue where BIOS POST might display the error message "Boot Manager recover from an error."

After rebooting, this appears on the screen:

    Found update fwupd-SOME-UUID-0
    File \EFI\debian\fw\fwupd-SOME-UUID.cap searched

So far so good. Then the screen goes blank for a while, then:

   Please wait while we install the update

After only a fraction of a second, however, the machine reboots, and the
firmware loads GRUB. After the system boots, poking about with
efibootmgr reveals that the entry for fwupdx64.efi is gone; as is the
cab file from /boot/efi/EFI/debian/fw.

So it looks like fwupdx64 thinks the firmware update suceeded when in
reality it didn't even begin.
