Resolution

Red Hat Enterprise Linux

Note: EUS is used below as an example. This resolution applies to all extended update streams (EUS, E4S, TUS, AUS) across RHEL 6, 7 and 8.

Use subscription-manager's "release" command to set the supported EUS minor version persistently

To determine which releases are available:
```
# subscription-manager release --list
```

To set a release:

# subscription-manager release --set=7.6
Release set to: 7.6

# yum clean all
Loaded plugins: product-id, rhnplugin, search-disabled-repos, subscription-manager
Cleaning repos: rhel-7-server-eus-rpms

# subscription-manager repos --list-enabled

Available Repositories in /etc/yum.repos.d/redhat.repo

Repo ID:   rhel-7-server-eus-rpms
Repo Name: Red Hat Enterprise Linux 7 Server - Extended Update Support (RPMs)

Red Hat Satellite 6 & Red Hat Update Infrastructure

RHUI

Red Hat Update Infrastructure (RHUI) environments will need to enable and sync the minor release repositories for Extended Update Streams and ensure that the repositories are added to the client certificate, if not already.

RHUI Clients are required to set their release using a tool that comes with the client certificate bootstrap RPM. Please refer to the This content is not included.RHUI Documentation (Working with EUS) for more information.
```
# rhui-set-release --set <version>
```

Satellite 6

Satellite environments will no longer be able to enable or synchronize "xServer" releases of Extended Update Streams

If you already have enabled and synced this content previously, it will continue to be accessible by your content hosts, but can no longer be synced for new content.

Proper resolution and configuration for a Satellite environment:

Enable and sync the specific minor releases you want to offer to your content hosts, such as 'x86_64 7.7' for any given stream (ex. Red Hat Enterprise Linux Server - Extended Update Support)
Configure your content hosts release to be set to the release you are syncing and offering through the Satellite Web UI, or via subscription-manager release as shown above. This can be done via remote execution or other automation in your environment as well.

Root Cause

For non-extended update streams, the "xServer" (ex. 7Server) naming/version is used to indicate use of the latest available release.
This is not a supported path for any extended update stream available from Red Hat.

Extended Update Support (EUS) repositories must be set to a supported minor release.
The same follows for all other extended update streams available (E4S, TUS, AUS).

Please refer to the RHEL Life Cycle documentation and the Extended Update Support (EUS) Add-On for further details.

Diagnostic Steps

To see if a system is affected by this change, run the following command to check for extended streams:

# yum repolist -v | grep -e eus -e e4s -e tus -e aus
repo: downloading from remote: rhel-8-for-x86_64-baseos-eus-rpms
error: Status code: 404 for https://cdn.redhat.com/content/eus/rhel8/8/x86_64/baseos/os/repodata/repomd.xml (IP: 111.222.333.444) (https://cdn.redhat.com/content/eus/rhel8/8/x86_64/baseos/os/repodata/repomd.xml).

Any 404 indicated above, or repository as indicated with a match on 'eus', 'e4s', 'tus', or 'aus' indicates a system that needs to be configured for release for continued access to content from those repositories.

To check if a client is correctly configured to receive Extended Stream content, run the following check:
```
# subscription-manager release
Release not set
```
If your release is "not set" or "6Server", "7Server", "8", or any other "xServer" configuration and you are using extended support repositories, you will need to set your release as directed above.
