What make/model modem do you have? I am unable to reproduce this with a Huawei E3276.

[Diego A. Elizondo (diegoaez)]

Model: Huawei E303

It seems that the problem is related to the chosen connection manager, with pppd the app opens allowing to send messages and USSD codes but it does not have support to manage internet connections, and if I choose the Network Manager the app just closes

[Jochen (hajoeg)]

I can confirm the case

Can you guys please see the bug #1993076. It's pretty urgent. Thanks.

[Tin (tin-111)]

Seems that this bug isn't fixed yet - would be nice to do it. Thanks

[Graham Inggs (ginggs)]

If someone updates this bug as per the SRU Bug Template [1] and undertakes to do the verification, I'll upload a fix, but I have no hardware to test this myself.

[1] https://wiki.ubuntu.com/StableReleaseUpdates#SRU_Bug_Template

[Graham Inggs (ginggs)]

This issue was fixed in modem-manager-gui 0.0.20-4 in Kinetic.

modem-manager-gui (0.0.20-4) unstable; urgency=medium

  * debian/control:
    - new Maintainer.
    Thanks to Graham <ginggs> for your work on m-m-g!
    - bump 4.6.0 -> 4.6.1 (no changes needed)
  * debian/patches/: patchset updated (Closes: #1004258)
    - fix_segfault_on_DNS_entries.patch added

[Jochen (hajoeg)]

from my point of view the bug can be closed. Jammy has a now the package modem-manager-gui (0.0.20-5) and it works

[Graham Inggs (ginggs)]

Jochen, you can see on the page below that the version in Jammy is only 0.0.20-3

https://launchpad.net/ubuntu/+source/modem-manager-gui

[Tin (tin-111)]

As far as I see Jammy hast only 0.0.20-3. Jochen, where did you got your 0.0.20-5?

[Graham Inggs (ginggs)]

I've prepared a package for Jammy, including the two fixes from Kinetic, in a PPA:
https://launchpad.net/~ginggs/+archive/ubuntu/sru

Please test and let me know if it solves the issue.

[Tin (tin-111)]

Thanks for that - over here no change, same error messages.

[Jochen (hajoeg)]

Ohh, I must confess that I have stolen the package from Debian. I know, it is not advised to use Debian packages for Ubuntu, but it worked without any problems.

I remember now, it is a year ago, I found this notice:

 on 2022-08-03
Changed in modem-manager-gui (Debian):
status: New → Fix Released

so I checked Debian an used the package. On my last comment I was confused, I thought Ubuntu had meanwhile upstreamed that package.

[Tin (tin-111)]

But then you don't run Ubuntu version 22.04? Because with this so called "fixed" version there are dependencies which are not fullfilled with version Ubuntu 22.04.

[Jochen (hajoeg)]

I tell you, I am running 22.04 Mate. I have attached a screen shot from synaptic showing the dependencies.

[Tin (tin-111)]

Sorry to say, but this version modem-manager-gui 0.0.20-5 (amd64 binary) crashes with the same error messages on Ubuntu 22.04.3 LTS.
BTW which version has your NetworkManager?

[Graham Inggs (ginggs)]

Tin, you write "the same error messages", but yours in comment #15 are different to those in the bug description (and other posts).

[Miles Sharpe (msdomdonner)]

Affects me too. Using 22.04 and dlink dwm-222 modem in south africa

[Miles Sharpe (msdomdonner)]

Can you pleas email me when the fix is in Ubuntu 22.04 upgrades
Thank you

[LufoX11 (lufox11)]

I'm joining the request. Ubuntu 22.04 with latest updates:

$ apt list --installed | grep modem-manager-gui

modem-manager-gui-help/jammy,jammy,now 0.0.20-3 all [instalado, automático]
modem-manager-gui/jammy,now 0.0.20-3 amd64 [instalado]

I'd like to use the connection manager from modem-manager-gui instead of Ubuntu's since I'm using alternative X managers, some very rustic with (almost) no gui, so I can't control network manager that easy.

If there's no plan to include the fix in 22.04, what official PPA should I subscribe to? Thanks
