Resolution

  1. As GPG armor is not enabled on server side, so ensure repo_gpgcheck is set to 0 in yum.conf file for RHEL clients.
    • NOTE : repo_gpgcheck either 1 or 0 tells yum whether or not it should perform a GPG signature check on the repodata. When this is set in the [main] section, it sets the default for all repositories. The default is 0.
  2. Now run yum update to confirm.

Root Cause

  • Currently Red Hat products (Customer Portal, Red Hat Satellite, RHUI, etc) does not support repo gpgcheck option yet.
  • yum was trying to download repomd.xml.asc and repo_gpgcheck was set as 1.
  • As yum was unable to locate repomd.xml.asc on the server due to GPG armor disabled, it was failing with [Errno 14] HTTPS Error 404 - Not Found error message.
  • On RHEL 7.4, the stig-rhel7-disa profile will add "repo_gpgcheck=1" to /etc/yum.conf.
  • Component
  • yum
