ubuntu software center won't start (window shows up and quits quickly)

[Zied Kallel]

Tried the following but none of them worked:

sudo apt-get update
sudo apt-get install --reinstall software-center
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install python-simplejson

Would greatly apreciate it if the answer gets emailed to me <email address hidden>

Cheers to you,
Z

What happens when you run 'software-center' in a terminal?

[Zied Kallel (zied-kallel)]

Samething happens! The application window pops up for one or two seconds than closes. In the terminal several lines of messages appear (probably too long to copy in this message box). Especially, this erros message is repeated 3 times:

AttributeError: 'ProgressBar' object has no attribute 'set_data'
Thanks,
