make sure you add your user to the right group, I think network group then reload dbus. what is the output of % id?

    Wat-now
    You mean 66 reload dbus?
    I just noticed that if i call ´connman-gtk' as super user it opens as expected.

      I suspect this is related to the new dbus release as well. Update to dbus 1.16.0-4 and see if the problem continues

        Wat-now
        Updated and restarted. The problem persists.

        sudo connman-gtk works although the window is not dark like the system theme.
        I also tried changing theme but i got no result

            igorka67 do you have a dbus group and user? what's the output of %id dbus

                igorka67 can you confirm that network manager works for you too? Of course you have to enable the 66 service too.

                    Maybe it won't help, but I just tried to rebuild the upstream. If you update, you can see if that helps. But judging by the errors above, it's likely something else.

                          My WiFi is working and if i launch connman as root it works...

                            nfg
                            The Song Remains The Same... ;-)

                              Yeah, same, the app just works if run with sudo. My wild guess is that the dbus new release has some issue with connman, being the latter kinda old software it wouldn't come as a surprise...

                              igorka67 yeah, I just tried to use network manager instead of running connman as sudo, it looks like NM has no issues, it runs as user :)

                                                  You would probably need to reinstall connman itself to repopulate /etc/connman. FWIW, my just contains main.conf whose contents are [General] followed by a bunch of commented out text.
