[Bug 1980334] Re: Support Quectel's modem(EM120/160) firmware update, fwupd

[Mario Limonciello]

1.8.3 (jammy)
-----
My apologies but for Jammy, I think the changelog will need a few more things.  These are both expected from my perspective, but they may be jarring/surprising to users and should be documented explicitly on the backport.

1. There was a jump up on the plugin ABI (libfwupdplugin5 -> libfwupdplugin7).  That is going to mean a NEW package for an archive administrator to process.
2. The logitech plugin is now activated.  This was intentional due to https://bugs.launchpad.net/ubuntu/+source/protobuf-c/+bug/1956617 .  This is going to mean that protobuf-c is now promoted from universe to main.  This happened in kinetic, but will also need to happen in Jammy now.

Can you document them in the changelog too?

1.7.9 (focal)
-----
To get the package order right with the rebuild, please make sure:
* fwupd has an explicit build-depends on the correct new libxmlb version in debian/control
* gnome-firmware has an explicit build-depends on the correct new fwupd version in debian/control
* gnome-software has a explicit build-depends on the correct new fwupd version in debian/control

Then that should mean libxmlb builds first, then fwupd, then g-s/g-f.

Bug description:
  [Impact]

   * EM120/160 firmware update's fw can't get updated.

  [Test Plan]

   * Use a machine with EM120/160 and test fw upgrade or reinstall.

  For the rest of the SRU document, please check lp:1982103

  Note: the SRU of fwupd is following the exception in
   https://wiki.ubuntu.com/firmware-updates. We also need to
   upgrade libxmlb due to fwupd is its only major consumer,
   and without that, we could not have the correct fwupd function
   on this one.

  The current fwupd packages in focal have to be rebuild with the latest 1.18.6 modem manager[1] in updates channel.

  In the modem-manager plugin of fwupd, there are several version check
  macros to determine the version of modem-manager, for instance:

  https://git.launchpad.net/ubuntu/+source/fwupd/tree/plugins/modem-
  manager/fu-mm-device.c?h=ubuntu/focal-updates#n22

      #if MM_CHECK_VERSION(1, 17, 2)
      #include "fu-firehose-updater.h"
      #endif

  If the version is equal to or newer than 1.17.2, fwupd will have
  different behaviors. And the previous version in Focal is 1.16.6 so we
  have to rebuild or do a version bump to make sure it compile with the
  new modem manager.
