[ubuntu] Software-center doesn't work

view story

http://ubuntuforums.org – Hi, i have version 10.04 of Ubuntu, Lucid Lynx, and when I run the software-center from menu -> Applications looks set to open in the taskbar, but after a few seconds disappears and does not open. Running it from the shell I get the following: Code: software-center Traceback (most recent call last):   File "/usr/bin/software-center", line 78, in     from softwarecenter.app import SoftwareCenterApp   File "/usr/share/software-center/softwarecenter/app.py", line 44, in     from view.installedpane import InstalledPane   F (Hardware)
