Could someone please help?
In your [start button] or whiskers menu type in "software & Updates"
go into your [Other Software] tab and find the one that says opensuse.org in the description (scroll down if necessary)
untick that source and allow it to refresh then do the update again to see if that solves that problem. (write down which one you unticked)
unless you want to keep it?
