Comment 5 for bug 688682

Hey Joda and other reporters. This bug can happen if the directory ~/.cache/software-center is created with root ownership somehow (see bug 652151 for some possible scenarios for how this might happen).

The fix is to set the ownership if this directory back to your user account. You can do this by typing the following into a terminal window (be sure to substitute your own username as noted below):

    sudo chown -R yourusername:yourusername ~/.cache/software-center

After this, Software Center should launch correctly. Please let us know if you have any troublem and thanks for your report!
