I attempted to reinstall the Ubuntu Software Centre after upgrading my graphics card and installing a new driver. I then found that Software Centre no longer did anything when clicked. So I removed it and reinstalled it. Below is a capture of my terminal window when the install failed. Selecting previously unselected package libgrilo-0.2-1:amd64.
