Screenshot of error

Using KDE Neon with latest KF5:

Qt: 5.9.1
KDE Frameworks: 5.40.0

In KStars, we use KAuth to download files to /usr/share/astrometry. After download is complete, it presents a root password dialog and after password is submitted, it displays the attached error.

There is already a .service file in the correction location.

/usr/share/dbus-1/system-services/org.kde.kf5auth.kstars.service

[D-BUS Service]
Name=org.kde.kf5auth.kstars
Exec=/usr/lib/x86_64-linux-gnu/libexec/kauth/kauth_kstars_helper
User=root

dbus-daemon is already running. Also dbus-launch

Is this still a problem? Sounds a bit like a setup problem, for polkit to work correctly there need to be 3 different files in the correct paths (the dbus policy to allow claiming the service name, the dbus service for dbus-invocation, the polkit actions to setup the actual auth). The file you mention is only the second bit and will not work without the first bit.

We stopped using it, so I'll close this.
