Whenever I run the rqt_graph command the following error appears in my terminal: loading plugin "qt_gui_cpp/CppPluginProvider" failed:
Traceback (most recent call last):
  File "/opt/ros/kinetic/lib/python2.7/dist-packages/qt_gui/", line 57, in discover
    instance = self._plugin_provider.load(plugin_descriptor.plugin_id(), None)
  File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_gui/", line 92, in load
    return class_ref()
  File "/opt/ros/kinetic/lib/python2.7/dist-packages/qt_gui_cpp/", line 43, in __init__
    RosPluginlibPluginProvider(qt_gui_cpp.RosPluginlibPluginProvider_ForPlugins('qt_gui', 'qt_gui_cpp::Plugin')),
TypeError: RosPluginlibPluginProvider_ForPlugins(): argument 1 has unexpected type 'str'

However the window does pop up with all the nodes and topics listed. Do I need to worry about this, if so, what is the fix ??

I tried looking for fixes online and have already tried:

sudo apt-get install ros-kinetic-rqt ros-kinetic-rqt-common-plugins


tried to reinstall qt_gui_core as the qt_gui_cpp seems to be a part of the qt_gui_core. But the install doesnt happen as qt_gui_core is not found.

Thanks in advance, A noob
