Ubuntu Software center in Ubuntu 13.04 crashes when opened
Solution 1:
Run this command in terminal. It will re-install the software-center and reset your settings.
sudo apt-get install --reinstall software-center
But for reconfigure a program you can use:
sudo dpkg-reconfigure software-center --force
Solution 2:
I also had software-center crash on launch after the Ubuntu 13.04 upgrade. It turned out to be in import error in the ubuntu-sso-login. I resolved it by reinstalling the oauthlib python package
sudo pip install --upgrade oauthlib
Solution 3:
I had same proble which I solved by deleting /home/user/.cache/software-center folder.
