I am running SuSE 10.1, x86_64 version This was a fairly recent clean install. Everything was working fine, including zen-updater, as I had installed 10.1 after a number of the zen-updater patches were released. I went away for two weeks and turned off my computer. Upon returning to work, when I first turned on the computer, zen-updater gave the following error message. System.NullReferenceException: Object reference not set to an instance of an object in <0x003d9> Novell.Zenworks.Gui.ZenTrayIcon:CheckUpdatesLoop () in (wrapper delegate-invoke) System.MulticastDelegate:invoke_void () This same error message appears if I enter "zen-updater" from the command line. I did Google for the error message but didn't find anything applicable. Not that big a deal as I could use the Online Update feature of Yast. This morning, however, when I entered Yast, I found that I could no longer use a number of the modules under YAST -> Software Online Update, Software Management, and Installation Source all give the same result when clicking on them. The Window opens briefly and then shuts immediately. Thus it is no longer possible to install software using Yast, change an installation source, or run YOU. I did apply some updates a couple of days ago using Yast. The software is basically standard SuSE 10.1, with the exception of a couple of packman items. In attempting to fix the zen-updater problem, I did check zen and zen-updater to make sure I ahd the latest versions. In installing those YAST indicated I had a conflict with something like "scriptlibzypp.noarch" That isn't exact, but it did have script, noarch and libzypp in the name. I resolved the conflict by checking off the choice not to install the script package. Now that I have typed this, it occurs to be that I should run YAST from runlevel 3 and see if it works there, or what error message it gives. Mike -- Michael A.
