    Fedora 29 - dnfdragora Error

    Hi Everyone,
    I am quite new to the Fedora setup and have been testing Fedora 29 KDE version in virtualbox.
    Installed Fedora 28 KDE and updated from that to the branched version.
    I think Fedora provides a good combination of latest software and stability..
    Most of the stuff works quite well without any issues, but the software center just does not work.

    When I start dnfdragora from the menu, I get the error that dnf is locked by another application.
    I googled and searched in the forums and found the command to exit from the terminal.

    So once that error gets fixed, I keep getting the below error.
    There is no end to this below error...I have tried reinstalling dnf, distro-sync dnf but for some reason it is not getting fixed.
    Requesting your help in working around the below error.
    dnfdaemon client error occurred:
    g-io-error-quark: GDBus.Error:org.freedesktop.DBus.Python.AttributeError: Traceback (most recent call last):

    Thanks and Cheers,

    You can omit last package if it is not installed.
