Repository not working - 404 error

Solution Verified - Updated

Environment

Red Hat Satellite 6.x up to 6.9

Issue

I recently upgraded our soon-to-be new satellite server to 6.4. Upgrade was fine and everything works normally except for the RHEL 7 Supplementary repo. It is enabled, newly synced, but when I go to a VM and try to do a yum update it fails with HTTP 404 error for the Supplementary repo. I can see it enabled and synced in Satellite WebUI.

Resolution

There are two options, depending on the customer's environment:

  1. If the customer has a second satellite server, then you can use the same /repodata/repomd.xml file from the same path. The reason that this works is that the XML file contains identical checksums for the files listed.
  2. If the customer does not have a second satellite server, then they can proceed through the process of removing the repository from content views, activation keys, etc, and then remove the content from the satellite, then re-sync the repository. This should pull down the /repodata/repomd.xml portion of the repository.

In either case, the repository would need to be removed from the content view(s), a new version of the content view(s) be published and promoted. Then, proceed with either of the above options, then add the repository back to the content view(s), publish a new version of the content view(s), then re-populate the yum cache on the host.

Root Cause

The satellite server did not have the /repodata/repomd.xml file in the repository's path. All of the packages were there, but the repomd.xml file was not present.

Diagnostic Steps

We found that content was missing the /repodata/repomd.xml from the path, so the 404 error is valid. 

# yum repolist enabled
Loaded plugins: langpacks, product-id, subscription-manager
https://example.satellite.com/published/content/dist/rhel/server/7/7Server/x86_64/os/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
Trying other mirror.

Checking the satellite server, the packages are there, but the /repodata/repomd.xml file is not.
