I installed Digikam for Ubuntu and unaware that the plug-in was already in Digikam, downloaded the KIPI and tried to install. My best guess. Here is the error from, apt-get;;

I was confused by a reference to KIPI plug-in for Ubuntu, and no mention of KIPI is already installed. Is KIPI being in Digikam now accepted as being the standard?
