Modem Manager failing to access modem and showing errors

Kris1 · May 19, 2023, 9:16pm

I am using “modem-manager” Snap on a Ubuntu Core 20 system running “lenovo-wwan-dpr” and “quectel-firmware-switch” and it cannot detect the modem. It worked once, detecting the modem, but then stopped.

By “worked” I mean I could call sudo mmcli -L and it would show the modem. Now, it just shows No modems were found message.

This Ubuntu Core 20 machine is a tiny, transactional edition of Ubuntu,
designed for appliances, firmware and fixed-function VMs.

If all the software you care about is available as snaps, you are in
the right place. If not, you will be more comfortable with classic
deb-based Ubuntu Server or Desktop, where you can mix snaps with
traditional debs. It's a brave new world here in Ubuntu Core!

Please see 'snap --help' for app installation and updates.

Why are there errors with modem-manager & why can’t it find the modem anymore?

ruhan.vanderberg · May 20, 2023, 8:30pm

Hello, it appears to be a confinement issue? Apparmor seems to be blocking the “PCI” subsystem from being accessed, and possibly even the serial ports or something.

Just make sure that all your modemmanager’s plugs is connected to all the slots…

From what I can tell all of the modem-manager plugs are connected to all the slots. Here is what is looks like:

I think that this shows all the plugs and slots are connected. Can you verify?

Kris1 · May 22, 2023, 5:02pm

@ruhan.vanderberg I noticed that after some time of installing Ubuntu Core, it performs a “snap refresh” automatically. After this “snap refresh” the modem is no longer detected.

Here is the versions of snap apps before the update

Here is a list of the versions after the update:

If I just update the “lenovo-wwan-dpr” app, it still detects the modem. The other snaps must cause the issue.

How do I go further with debugging?

ruhan.vanderberg · May 23, 2023, 6:54am

Then something must have been broken between ModemManager version 1.16.6-2 and 1.18.6-2. Not sure how I would debug further.

You could probably look at snap changes and snap change [id] for more details, but I don’t think that it is related on your system, probably some broken package or component that must have slipped in somewhere.

Kris1 · May 23, 2023, 1:43pm

@ruhan.vanderberg where would you recommend I post these findings to get the right eyes on it:

Modem Manager GitLab, submit issues: https://gitlab.freedesktop.org/mobile-broadband
ModemManager-devel list: https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel

Or another place?

ruhan.vanderberg · May 23, 2023, 1:45pm

I am not currently employed by Canonical, so probably best to ask @ogra to point you in the right direction in reporting/filing a bug…

ogra · May 23, 2023, 2:00pm

let me summon @abeato

Kris1 · May 24, 2023, 3:27pm

@ogra & @abeato how does this work in production?

Ubuntu Core is a immutable OS that is aimed at “far edge” devices such as IoT gateway (in my case). If the Snap updates cannot be turned off & the latest Snaps are always installed, then it is a high possibility that all the edge devices like let’s say you have 10,000 of them will loose internet connectivity. This means I would have to buy plane tickets, hotels, car rentals, and go and fix this issue. Especially, for devices that only have cellular connectivity.

How could I protect against updates killing internet access to the devices?

ogra · May 24, 2023, 3:34pm

you can turn off snap updates using the hold command …

particularly in IoT you’d use a brand store for your device though, this gives you even more features to bundle snaps into a validation set or to use a gating snap that makes sure updates only happen once you approve them after a test.

in general i think alfonso keeps the network-manager and modem-manager channels in sync tough so as long as you use the same channels for a version you should never run into trouble … (but that is up to alfonso to answer in detail, i don’t know the specifics here)

Kris1 · May 24, 2023, 6:06pm

@ogra thanks for the feedback. What is the best way to submit an issue to get the cellular modem to be detected again. With the latest Snap’s it is showing:

user1-company@ubuntu:~$ sudo mmcli -L
No modems were found
user1-company@ubuntu:~$

Is there a place where I can send the log that I can get using the command below:

sudo journalctl | grep -i modem

There is a way to enable debug output with Modem Manager by creating a .debug_enabled file:

May 24 18:01:26 ubuntu modem-manager.modemmanager[938]: + export SNAP_APP_PATH=/snap/modem-manager/523

May 24 18:01:27 ubuntu modem-manager.modemmanager[938]: + [ false = true ]

What would be the best way to get this modem to be detected again?

ogra · May 24, 2023, 6:22pm

i’d file it (from the package description) under:

but make sure that you run both packages from the channel matching your core snap … i.e. on UC20 use them from the 20/stable channel, likewise for UC22 the 22/stable channel …

abeato · May 25, 2023, 10:37am

Hi, something strange that I see here is that the network-manager version is not updated when you update all the snaps, could you please make sure that happens? Apparently that snap is hold for some reason (maybe validation or using --hold?). The version you want is:

  20/stable:        1.22.10-19     2023-05-16 (829) 5MB -

as updating network-manager was actually needed after moving MM from 1.16 to 1.18.

Kris1 · May 25, 2023, 12:52pm

@abeato I reinstalled Ubuntu Core on the system and it updated itself. Notice that MM is 1.18 and NM is 1.22 from “20/stable” and yet the modem is not detected:

Why is it not detect if all the matching versions of MM and NM are there?

ogra · May 25, 2023, 2:04pm

could you check change #3 ? did that perhaps include also the kernel snap (not sure where that comes from, i only know the pc-kernel snap as our official x86 kernel, the intel-kernel might have a slight different patch-set and perhaps also different drivers ) ?

Kris1 · May 25, 2023, 6:35pm

@ogra I will try to get this to you tomorrow because I wiped out the SSD on that system. I’m testing several OSes for an IoT base OS.

I will put Ubuntu Core on it and leave it overnight and check to see if the same changes are shown.

abeato · May 26, 2023, 12:08pm

Looking at the first logs, I see a lot of failures while running snap-device-helper, which add devices to cgroups and would explain the failure to detect the modem:

May 19 20:42:50 ubuntu systemd-udevd[494]: ttyS27: Process '/usr/lib/snapd/snap-device-helper add snap_modem-manager_mbim-network /devices/platform/serial8250/tty/ttyS27 4:91' failed with exit code 1.

Which implies that is not something directly related to the modem-manager snap, but something strange with the device configuration. Maybe the refresh of snapd triggered the problem. To spot where the issue actually is it would make sense to refresh snap by snap, and check how is the behavior after a restart of the modem-manager services.

Kris1 · May 26, 2023, 1:15pm

@abeato this modem is “special” because it needs this lenovo-wwan-dpr snap for it to work. Maybe this interactions with lenovo-wwan-dpr and modem-mangager.

What do you recommend in terms of the order of updating the snaps?

Kris1 · May 26, 2023, 1:17pm
