For additional hardware support, modemmanager needs to be upgraded to 1.10 on Bionic

[Till Kamppeter]

[Impact]

 * The new modemmanager package adds DW5820e and DW5821 support.
 * This modemmanager version is needed to support new devices.

[Test Case]

 * install modemmanager, libmbim, and libqmi from -proposed
 * reboot and try WWAN function to see if any regression there.
 * perform general dogfooding of its reverse dependencies (network-
   manager, gnome-control-center etc.)

[Regression Potential]

 * The package comes from Disco and should not have regression there.
 * Every new upstream release can potentially break existing dependencies
   if any of the required features have been changed/removed, so besides
   regular testing a general dogfooding session with the new modemmanager
   is advised.

[Original Description]

To have Bionic, the current LTS, working with as wide of a range of modems as possible we need to have it upgraded to the current 1.10 versions. Also the underlying libraries need to get upgraded appropriately.

[Till Kamppeter (till-kamppeter)]

Added tasks for libmbim and libqmi as their current versions are needed by ModemManeger 1.10.

[Till Kamppeter (till-kamppeter)]

debdiff for modemmanager 1.10 in Bionic. The upstream source tarball is the same as for Disco.

[Till Kamppeter (till-kamppeter)]

debdiff for libmbim 1.18.0 in Bionic. The upstream source tarball is the same as for Disco.

[Till Kamppeter (till-kamppeter)]

debdiff for libqmi 1.22.0 in Bionic. The upstream source tarball is the same as for Disco.

[Till Kamppeter (till-kamppeter)]

I have made Bionic packages for ModemManager 1.10 and the needed libraries now. I have attached the debdiffs and the upstream tarballs are the same as of the Disco packages.

Ken, could you upload these packages for me.

Alex, if we need to go through the SRU process (is this needed for hardware enablement), could you add the info about impact, reproducer, regression potential, ...

[Till Kamppeter (till-kamppeter)]

Replacement for the debdiff for libqmi 1.22.0 in Bionic.

This debdiff also contains the most recent fixes In Debian and in Disco (see https://bugs.launchpad.net/ubuntu/+source/libqmi/1.22.0-1.2):

----------
libqmi (1.22.0-1.2) unstable; urgency=medium

  * Non-maintainer upload.
  * Add debian/patches/git_reset-offset-before-2nd-call.patch from upstream.
    - equivalent to 1.22.2 release except the broken manpages in that release.

 -- Andreas Henriksson <email address hidden> Tue, 12 Mar 2019 14:19:35 +0100

libqmi (1.22.0-1.1) unstable; urgency=medium

  * Non-maintainer upload
  * Bump Build-Depends on libmbim-glib-dev to 1.18.0 to fix build
    (Closes: #921321)

 -- Jeremy Bicha <email address hidden> Thu, 07 Feb 2019 18:22:46 -0500
----------

The patch solves a regression from 1.10 which made some modems not work.

[Till Kamppeter (till-kamppeter)]

Yuan-Chen, Alex: I have finished to prepare the three needed packages, including a fix on libqmi coming in yesterday. Now I am simply waiting for the upload of the packages getting sponsored (probably by Ken VanDine) and the SRU team putting the packages into bionic-proposed.

Feel free to add anything relevant for testing the package to the description of this bug report.

[Ken VanDine (ken-vandine)]

The libqmi debdiff doesn't include the latest version that's in bionic (1.18.0-3ubuntu1) in the changelog and it also reverts the change in that version. Please ensure the debdiff is against that version.

[Ken VanDine (ken-vandine)]

The libmbim debdiff doesn't include the latest version that's in bionic (1.14.2-2.1ubuntu1) in the changelog and it also reverts the change in that version. Please ensure the debdiff is against that version.

[Till Kamppeter (till-kamppeter)]

[Till Kamppeter (till-kamppeter)]

Fixed libmbim package.

[Till Kamppeter (till-kamppeter)]

per test in bionic, turn on proposed channel, do a 'apt install modemmanager'. it will upgrade to version 1.10.0-1~ubuntu18.04.1 and also upgrade related libmbim and libqmi library.

I do that separate on two machine, that have DW5820e and DW5821e separately with a sim card inside.

I confim I can properly add a new connection and connect to internet successfully.

Note: for today, need to set DW5820e to USB mode in BIOS per information from HW vendor.

i am very happy to try any fixes helping to try different versions to see where the regression was introduced.
thanks.

[Till Kamppeter (till-kamppeter)]

yparitcher, as this SRU consists of three packages, ModemManager itself and the two libraries, try at first to downgrade only modemmanager to the original. If this solves the problem, it is caused by modemmanager, if not, downgrade one of the libraries, then try to downgrade the other, ... until you could spot one of the three packages having caused your problem.

[yparitcher (yparitcher)]

i downgraded ModemManager back to 1.6.8-2ubuntu1 and the problem went away, so it is caused by ModemManager.

yparitcher, thank you for the upstream bug report. As soon as upstream finds a (backportable) solution we will add it to this SRU and report back here.

[Till Kamppeter (till-kamppeter)]

yparitcher, thank you very much for your fix. We will add it to the SRU of the modemmanager package and also apply it to eoan. Please watch out this bug report for a new verification call.
To the SRU team: The regression of the modemmanager SRU is fixed and I will soon put up a new debdiff for upload. The two libraries (libmbim and libqmi) did not cause any regression. Please do not remove them from -proposed as they are still needed for the modemmanager SRU.
yparitcher, could you open a Launchpad bug report for your regression/fix for eoan and SRUs on disco and cosmic? Thanks.

[Till Kamppeter (till-kamppeter)]

debdiff to fix the regression in eoan.

[Till Kamppeter (till-kamppeter)]

yparitcher, first, thanks for reporting bug 1828102, we need this separate bug as Cosmic and Disco originally came with ModemManager 1.10 and so did not suffer the bug treated here, only the regression which you have found. Eoan I have already treated here as the SRU team requires that the issues which are fixed by an SRU are also fixed in the current development cycle.

yparitcher, please test the new modemmanager package in bionic-proposed on your Bionic systems to see whether the regression is actually fixed and report back here. Thanks.

[Till Kamppeter (till-kamppeter)]

Alex Tu, please test the new packages in bionic-proposed whether they correctly support the modems for which you asked for support for. Thanks.

[yparitcher (yparitcher)]

regression fixed in 1.10.0-1~ubuntu18.04.2

however please note now that ModemManager is started by default with filter-policy=strict in order for MM to see Bluetooth modems you need a udev rule like such:

Has this been performed with modemmanager 1.10.0-1~ubuntu18.04.2 please?

Also, there's a dep8 regression reported (https://people.canonical.com/~ubuntu-archive/pending-sru.html). Please could someone look into that?

Robie was referring to the autopackagetest failure for network-manager

[Till Kamppeter (till-kamppeter)]

This autopkg test failure does not look much as induced by ModemManager. Could someone with appropriate right re-initiate it? Thanks.

The network-manager SRU 1.10.14-0ubuntu2 is in -updates now and the autopkg test got successfully repeated with it, so this SRU can be tranferred to -updates, too.

[Chris Halse Rogers (raof)]

Gah. Sorry about not picking this up on my first pass through, but what's happening with Cosmic here? As far as I can tell, this also applies to Cosmic (but not Disco), and Cosmic is still supported for a couple of months (long enough that I'm hesitant to go “sure, we don't need to worry about it”).

[Ken VanDine (ken-vandine)]

@roaf: This was driven by an OEM request, so the priority was bionic. We also needed to make sure disco (and later) was covered to ensure we made the next LTS as well.

[Łukasz Zemczak (sil2100)]

We should think about cosmic indeed, but it's not really blocking the release for bionic. Currently upgrades from bionic to cosmic will very very very rare. With disco released, there's no 'official' upgrade path - not to mention bionic users by default should be only informed of new LTS versions. So I'll proceed with getting this out.
