Repository ?

Hi. I'm upgrading my SuSE 10.0. Then I receive this: Cannot access installation media Packman (SuSE LINUX 10.0) CD 1. Check that the server is accessible. http://packman.iu-bremen.de/suse/10.0 The source at the specified URL now provides a different media ID. If the URL is correct, this indicates that the source content has changed. To continue using this source, start Change Source of Installation from the YaST control center and refresh the installation source. The URL is ok, but how can Packman not be found ? Erik Jakobsen
