[Bug 1820768] Re: [SRU] support new cab and new docking firmware upgrade in fwupd 1.2.5

[Yuan-Chen Cheng]

A firmware download from lvfs is in cab format.

We can use the command "fwupdmgr install [--allow-reinstall] file.cab",
and a reboot to install it. [it could brick your computer, don't do it
unless you have someone to save you.

fwupd                                                            1.0.9-0ubuntu2
libfwupd2:amd64                                                  1.0.9-0ubuntu2 

There is not libfwupd2-dev package.

We can also use gcab to extract firmware.bin from the cab file. You need
to get guid from "fwupdate -l" and then command "fwupdate -a guid
firmware.bin" and a reboot can install it.

fwupdate                                                         12-3bionic2
fwupdate-signed                                                  1.19bionic2+12-3bionic2
libfwup-dev:amd64                                                12-3bionic2
libfwup1:amd64                                                   12-3bionic2

As replace fwupdate-signed by fwupd-signed, we also need to make sure
the command "fwupdate -a guid firmware.bin" is compatiable with fwupd-
signed per what I understand.

Bug description:
  * Impact

  Bios vendor is pushing to put the new design into cab file, and also
  new docking DW19 needs the new fwupd to support it.

  That needs new fwupd to support.

  * Test case

  I
  1. install the new fwupd, and plugin the new docking - DW19.
  2. fwupdmgr get-devices and check if all internal device can properly show
  II.
  1. If you can get new cab file, try to use fwupdmgr install XX.cab to see if can work properly.
  III.
  1. If you can get a machine that have some firmware update pending, try to go gnome-software, and click refresh with the new fwupd, you should be able to see the pending firmware showed there. Which proves that it can properly integrated with gnome. (ycheng-twn have a laptop with that condition, and he can verify that one)

  
  * Regression potential

  Since the upstream maintainer is back up this upgrade, and he also
  works in a major computer vendor and works closely with the BIOS team,
  it should be fairly low risk.
