Status changed to 'Confirmed' because the bug affects multiple users.

Same on Ubuntu 18.04 (4.18.0-20-generic), Modem Manager Gui(0.0.19.1-1).
This bug probably revealed another one – Modem Manager Gui prevents from suspend on Ubuntu 18.04 when mobile network connected and no WiFi connection.

This sounds a lot like Debian bug #922608 [1] which is fixed in Eoan.

Disco got modemmanager 1.10.0-1 on 2019-02-23, and Bionic got the backport on 2019-05-16.

Please try the version of modem-manager-gui from my PPA [2] and if this solves the problem we can prepare a Stable Release Update for Disco and Bionic.

I've since updated to Eoan. Don't know under what circumstances the bug triggers exactly but startup here appears to work currently.

Hi Graham, I have installed modem-manager-gui from your PPA. It solves the problem. But unfortunately my problem with suspend is still present.
Modem-manager-gui in specific circumstances blocks system from suspend.

I don't think Cosmic needs to be targeted as it does not have modemmanager 1.10.

The "Regression Potential" portion of the SRU template is to indicate how things might go wrong to improve testing of the Stable Release Update. Can you please update the regression potential with something that meets that criteria?

Hello David, or anyone else affected,

Accepted modem-manager-gui into disco-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/modem-manager-gui/0.0.19.1-1ubuntu0.19.04.1 in a few hours, and then in the -proposed repository.

Hi Timo, is this package the same that was in Graham PPA https://launchpad.net/~ginggs/+archive/ubuntu/sru? I've already tested it and it fixes the bug.

Hi Jan
Yes, this package should be identical to the one in my PPA, but please test again with the official version from the archive.

Would you be willing to test the Disco version as well please? I am unable to do the verification as I don't have an affected modem.

modem-manager-gui (0.0.19.1-1ubuntu0.18.04.1) bionic-proposed – tested, fixes the bug.

Graham, I'm on Bionc. Can I test the disco package on bionic?

Jan, no the Disco package needs to be tested on Disco. If you don't have access to another computer, a live CD, or virtual machine with USB pass-through could work.

We still need someone to perform the verification in Disco.

I tested in disco, 0.0.19.1-1build1 crashes as described, 0.0.19.1-1ubuntu0.19.04.1 does not.

This bug was fixed in the package modem-manager-gui - 0.0.19.1-1ubuntu0.18.04.1
