Since 2 weeks, my Novell Software Updater does NOT indicate any available update? I think the message/info is wrong as I receive a few notifications from Novell about new patches available.
Unfortunately nothing occured on my system. My account is active at Novell, so I should be able to download/install patches with no problem.
Verify a good network connection, eg ping your online repositories.
Are you behind a firewall, particularly a Proxy firewall? A Proxy firewall is more problematic than other firewalls, I’ve had problems passing proper credentials to the Proxy despite SuSE improvements (you can search the Forum for Proxy HTTP connectivity)
