It seems like I am getting some error related to Python, but I am not sure why I am getting it. When I ran Software Updater (in 12.10) from unity, it didn't even fire up.

When I did this from the terminal:

sudo update-manager

I am getting this trace, and update manager doesn't even open. I don't think this is a bug, so I am asking it here.

Traceback (most recent call last):

  File "/usr/bin/update-manager", line 28, in <module>

    from gi.repository import Gtk

  File "/usr/lib/python3/dist-packages/gi/repository/__init__.py", line 25, in <module>

    from ..importer import DynamicImporter

  File "/usr/lib/python3/dist-packages/gi/importer.py", line 24, in <module>

    import logging

ImportError: No module named logging

Error in sys.excepthook:

Original exception was:

Traceback (most recent call last):

  File "/usr/bin/update-manager", line 28, in <module>

    from gi.repository import Gtk

  File "/usr/lib/python3/dist-packages/gi/repository/__init__.py", line 25, in <module>

  File "/usr/lib/python3/dist-packages/gi/importer.py", line 24, in <module>

    import logging

ImportError: No module named logging

However, apt-get commands work fine. Python seems to be installed properly(?), so I can't figure out what the trace is saying. Any idea what can I do to get back update-manager working?
