Device not found while using flatpak

#1

Hello All,
I am new to flatpak and have started working to create flatpak package for WWAN enablement i.e flatpak package for Install lenovo-wwan-dpr on Linux | Snap Store

I am getting below error:

  1. sh: line 1: mmcli: command not found
    I am using “mmcli” to get modem type in Application code

  2. ls: cannot access ‘/dev/wwan*’: No such file or directory
    Above error is shown but i am able to see /dev/wwan0mbim0 files

yml file loiks like below:

app-id: org.flatpak.Hello
runtime: org.freedesktop.Platform
runtime-version: '21.08'
sdk: org.freedesktop.Sdk
command: DPR_test
finishing-args:
  - --share=network
  - --filesystem=/dev
  - --device=all
modules:
  - name: hello
    buildsystem: simple
    build-commands:
      - install -D DPR_test/app/bin/DPR_test
    sources:
      - type: file
        path: DPR_test

We are just packaging a binary using flatpak.
Any comment regarding this will be helpful:

Thank you !!

you should not have --filesystem=/dev

as for mmcli it’s not in the runtime as it doesn’t have ModemManager. You’d need to build in the flatpak.

@hub Thank you for your comments.

you should not have --filesystem=/dev

It seems application cannot access /dev/wwan0mbim0 file . Is there something needs to be done in yml file for this ?

You’d need to build in the flatpak.

In this case, i suppose i need to package ModemManager as modules . Is there any other application which uses modemmanager build in flatpak , so that i can re-use it as it will be very helpful.

Thank you

I had tried searching in github but cannot see any search result using above link as well, not sure any permission needed to see this. Thanks

@razzeee Thank you very much ! I will try and check it !!

For what it’s worth, the application you’re looking to package looks like a daemon that runs in the background. It’s unlikely to be accepted in Flathub if it doesn’t have any UI to speak of, contrary to snap and the snap store.

@hadess Thank you for sharing this information. Yes, this application doesn`t have any UI.
