Description of problem: This is a bug for hosted Z stream support. This bug occurred early June 2008 in RHN 5.05. Customer has a GLS instructor account and has access to Z-stream channels. On one system (has not attempted on others): 1) He attempted to switch from the mainline channel to the Z stream (5 mainline to 5.1 Z-stream) via the webui. While this provided an error message, it appeared to actually work and the 5.1 Z-stream appeared as the new base channel for the system in the webui. 2) Now that the system is listed as being in the 5.1 Z-stream, he can no longer move back to the mainline from the Z-stream. Attempts to do so do not change the base channel listed for the system. 3) "There seems to be some inconsistencys in the channels too, like yum install xen fails because of a missing dep on dnsmasq" 4) "yum grouplist does not give what I would expect, for instance no Virtualization group" 5) "there were other issues too, like no yum-utils for instance" --- I believe the Z-stream channel subscription logic is such that you cannot move from the baseline to a z-stream. You can start on a Z-stream though if you select the Z-stream when you register the machine. You may be able to move from mainline to the *latest* z-stream though. I'm not sure. I would assume that the dependency issues encountered were related to this protection of preventing movement from the mainline to the Z-stream not being enforced.
The only server in production registered to any 5.1.z channel, is the one I registered this morning to test. Can I have the sid of the affected server?
As you may already be aware, Red Hat is transitioning from the Red Hat Network (RHN) hosted interface to the Red Hat Subscription Management (RHSM) interface in July 2017. Red Hat has invested in and seen success from RHN for many years, and used that experience to build more robust technologies like RHSM. If you have not yet migrated your RHN systems to RHSM or you are a Red Hat Satellite customer, please review the information from. https://access.redhat.com/products/red-hat-subscription-management#migration. Since we are shutting down RHN, no further actions will be taken with this bug or enhancement request. You can find additional information at RHSM product page (https://access.redhat.com/products/red-hat-subscription-management).
