when I use sudo update-manager -c -d to update the system, it returns the following:

/usr/bin/update-manager:28: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
  from gi.repository import Gtk
Traceback (most recent call last):
  File "/usr/bin/update-manager", line 38, in <module>
    from UpdateManager.UpdateManager import UpdateManager
  File "/usr/lib/python3/dist-packages/UpdateManager/UpdateManager.py", line 43, in <module>
    import dbus
  File "/usr/lib/python3/dist-packages/dbus/__init__.py", line 82, in <module>
    import dbus.types as types
  File "/usr/lib/python3/dist-packages/dbus/types.py", line 6, in <module>
    from _dbus_bindings import (
ModuleNotFoundError: No module named '_dbus_bindings'

Can anyone please help me?

    Are all your packages updated? sudo apt update && sudo apt upgrade – Gunnar Hjalmarsson Jun 17 '19 at 14:07

    If you need to ask this question, reconsider using the -d flag. You may lack the skills to handle the consequences. -d will upgrade to the unstable, in-testing, pre-release version of 19.10...which we don't provide support for. – user535733 Jun 17 '19 at 15:56

To Update your Ubuntu do:
sudo apt update : Refreshes repository index
sudo apt upgrade : Upgrades all upgradable packages
This should upgrade all your current packages to the latest version.

If you are looking to upgrade your Ubuntu you can do that with :sudo do-release-upgrade
You can learn more about upgrading Ubuntu here.

If none of them are working, then there is a good chance that there is some issue in your "sources.list" located in /etc/apt/sources.list
