After upgrading to Ubuntu 12.10, unable to open update-manager

Asked by apinpratap

Recently I upgraded to Ubuntu 12.10, after that I am unable to open Update manager and software center. When I tried to open Update Manager by terminal it shows following error. Please help

Traceback (most recent call last):
  File "/usr/bin/update-manager", line 37, in <module>
    from UpdateManager.UpdateManager import UpdateManager
  File "/usr/lib/python3/dist-packages/UpdateManager/UpdateManager.py", line 52, in <module>
    from .InstallProgress import InstallProgress
  File "/usr/lib/python3/dist-packages/UpdateManager/InstallProgress.py", line 40, in <module>
    from .backend import get_backend
EOFError: EOF read where not expected
Error in sys.excepthook:

    from apport.report import Report
  File "/usr/lib/python3/dist-packages/apport/report.py", line 28, in <module>
    import problem_report
EOFError: EOF read where not expected

Original exception was:
Traceback (most recent call last):
  File "/usr/bin/update-manager", line 37, in <module>
    from UpdateManager.UpdateManager import UpdateManager
  File "/usr/lib/python3/dist-packages/UpdateManager/UpdateManager.py", line 52, in <module>

A similar looking problem in https://answers.launchpad.net/ubuntu/+source/update-manager/+question/213929 was solved by deleting all the *.pyc files under /usr/lib/python3/dist-packages/

Most probably deleting all of them in all directories is overdone, you might start with deleting them from /usr/lib/python3/dist-packages/UpdateManager/ and /usr/lib/python3/dist-packages/apport/ as a first attempt.

Can you help with this problem?
