  • cdn-sync is not able to list latest EUS channels.


  • Install the latest cdn-sync-mappings package on the Satellite server by running below commands:
  # yum update cdn-sync-mappings
  • Once the latest package has been installed please go ahead refresh the manifest on the satellite server:
  # rhn-satellite-activate --manifest-refresh
  • Now go ahead and sync the satellite server.

Root Cause

  • cdn-sync-mappings provides satellite information about available channels.
  • When a new channel is released by Red Hat its mapping is added into the latest version of this package. So it's important to patch satellite server with all available latest packages along with the cdn-sync-mappings package.

Diagnostic Steps

  • Check the installed version of cdn-sync-mappings package on the Satellite server:
 # rpm -qa |grep cdn-sync-mappings

It worked for my customer using the following command, after the procedures described in this kbase:

cdn-sync -c rhel-x86_64-server-7

Might be helpful to include or point to instructions for disconnected Satellites. Thanks.
