Running OpenSuse 12.3 with Gnome since spring of 2013. A month or so ago "Software Updates" quit responding when told to apply (the window for the administrator's password does not come up and the list of updates just 'sits' there - for hours), nothing happens. I read in a forum that PackageKit was at fault, but when I uninstalled it, Software Update would not even refresh (ie. would not show any updates available - the window would simply stay blank). Tried downgrading PackageKit, which did not help (so I upgraded it again). For some reason, Software Updates 'hangs' when I click on the 'install' button. Does anyone have any idea why this is happening?
