Created from redmine issue http://projects.theforeman.org/issues/5968

This fix only works for subscription manager versions greater than: subscription-manager-1.12.1

Prior to the above version, all requests for a system's available releases would go directly to the CDN (and thus should see no hit on the Katello server and the rhsm.log should show the CDN). After this version, querying for available releases should hit the Katello server and only return releases that in the system's content view the same as happens in the UI.

The sub-man command is: 

subscription-manager release --list

On the sat6 server side using the sat6-SNAP11-compose
[root@dhcp201-151 ~]# rpm -qav | grep -i subscription-manager

Me not sure, if something is missing. But do let me know if it is so. for now it looks like it's FAILEDQA.

Definitely an issue.

Looking at the log, subscription-manager seems to be doing what it should be. The root resource exists for available_releases, and a call is being made to katello for the release versions. Subscription-manager would be requesting them from the CDN directly, otherwise.

To me this appears to be an issue with the way katello is handling GET /katello/api/consumers/:consumer_uuid/available_releases

I wonder if katello is proxying this request directly to candlepin, instead of handling itself (as it should be). Candlepin does not implement that end-point, so if it were proxied, the 404 would occur from candlepin.

I have confirmed that this is happening on the katello side. The issue is that the route for GET /katello/api/consumers/:consumer_uuid/available_releases is included in v2 but not in v1 routing file. Candlepin proxied routes are handled by V1 routes and therefore it is not being matched.

Adding a match statement to config/routes/api/v1.rb will fix the issue.

NOTE: This is not broken in github master -- only beta.

Please re-test this on a more recent snap.

Tested with 
a) Sat6-GA-Snap4
b) subscription-manager-1.12.4-1.el6.x86_64
c) python-rhsm-1.12.3-1.el6.x86_64
