Ubuntu Software Center Crashes A Few Seconds After Opening [SOLVED]

If Ubuntu Software Center closes a few seconds after opening, then the solution given in this tutorial may help you fix this problem. Here are some outputs returned from the terminal when the application crashes:

  File "/usr/share/software-center/softwarecenter/ui/gtk3/views/appdetailsview.py", line 176, in __init__
    self.progress.set_data("transparent-bg-hint", True)
AttributeError: 'ProgressBar' object has no attribute 'set_data' 

To solve this problem, you can follow these instructions:

1. Open the terminal and edit this file:

sudo gedit /usr/share/software-center/softwarecenter/ui/gtk3/views/appdetailsview.py

2. Locate this line (line 176):

self.progress.set_data("transparent-bg-hint", True)

Comment it (add the # sign at the beginning of the line to disable it), then save your file and exit.

The bug will not occur again.

NOTE: This solution is workable under Ubuntu 12.04/11.10 or older.

Godd luck!
