My 1.1 Spacewalk server has stopped showing updates available for clients, even though running "yum check-update" on clients shows that several updates are available. The systems are CentOS 5.6, and I recall an email previously that said you might have to flush your channels due to a signature issue. I wasn't sure exactly how to flush the channels, so I just created new ones, moved the systems over and they saw their updates for a while. Now it's stopped again. Is there something else I need to change? Thanks. Kyaphas Hill Network Engineer CSC This is a PRIVATE message.
