Major changes since Uyuni Proxy 2021.12

Features and changes

Version 2023.03

Salt 3000 EoL

Upstream Salt 3000 went End of life on August 31, 2021. However, because it was part of the Advanced Systems Management Module of SUSE Linux Enterprise 12 and there was no bundle available for SUSE Manager 4.1, it was still supported.

Salt 3000 will no longer be supported in the context of Uyuni now that both SUSE Manager 4.1 and the Advanced Systems Management Module of SUSE Linux Enterprise 12 are End of Life.

Users are required to migrate existing Salt 3000 minions for SUSE Linux Enterprise Server 12, Red Hat Enterprise Linux 7, CentOS 7, Oracle Linux 7, and Amazon Linux 2 to the Salt Bundle before creating any bug reports.

For more information about performing Salt 3000 to Salt Bundle migrations, please consult the Salt Bundle section in the Client Configuration Guide.

Version 2023.01

Release notes cleanup

With Uyuni 2023.01, we are removing versions older than 2021.12 from the release notes, to make the document smaller and easier to review.

Release notes for older versions, up to 4.0.0 can stil be found at the website.

Version 2022.12

Bugfix release.

Version 2022.11

Bugfix release.

Version 2022.10

Bugfix release.

Version 2022.08

Proxy deployment with Helm Charts

Technology Preview: Helm chart to deploy containerized Uyuni Proxy and Retail Branch Server

Deploying Proxy and Retail Branch Servers as containers is now also possible using a Helm chart.

For more information check this README file. The information will be part of the Uyuni official documentation in a future release.

WARNING: The container images configuration has a new format and it is now packaged as tar.gz file. All previously deployed container Proxies and Retail Branch Servers will need to get their configuration regenerated and deployed again before pulling these images.

Version 2022.06

Upgrade notes

WARNING: This release updates the base OS from openSUSE Leap 15.3 to openSUSE Leap 15.4 and there are special steps required. You need at least Uyuni 2021.06 already installed to perform the upgrade, and you need to follow the (major upgrade procedure for the Proxy. More details are also available at the "Update from previous versions of Uyuni Proxy" section below.

WARNING: This release updates the Salt version for master and minions to a next major release. Make sure you update the Uyuni Server before updating the proxies, as backward compatiblity of minions against an older master is not guaranteed

WARNING: With Uyuni 2021.12, we announced the future deprecation of the Traditional client tools. Uyuni 2022.06 is the last release that supports them. Starting with Uyuni 2022.08, the traditional client tools will be deprecated as we will start removing the code at some point after the summer. Do not use the traditional stack for any new deployments of clients or proxies, and start migrating your traditional clients to Salt.

Base system upgrade

The base system has been upgraded to openSUSE Leap 15.4.

Salt 3004

Salt has been upgraded to upstream version 3004, plus a number of patches, backports and enhancements by SUSE, for the Uyuni Manager Server, Proxy, and Client Tools.

We intend to regularly upgrade Salt to more recent versions.

For more details about changes in your manually-created Salt states, see the Salt 3004 upstream release notes.

Salt Bundle 3004 will be available for all supported clients.

The non-bundle version of Salt requires Python3 instaled by default, so it will not be available for:

  • SUSE Linux Enteprise 12

  • CentOS 7

  • Oracle Linux 7

  • Red Hat Enteprise Linux 7

Version 2022.05

Bugfix release

Version 2022.04

HSTS available

HTTP Strict Transport Security (HSTS) is a policy mechanism that helps to protect websites against man-in-the-middle attacks such as protocol downgrade attacks and cookie hijacking.

Uyuni 2022.04 allows enabling HSTS. Which means each request will need to be HTTPS while plain HTTP requests will be rejected.

To enable it for the Uyuni Proxy:

  1. Edit /etc/apache2/conf.d/spacewalk-proxy.conf

  2. Uncomment the line # Header always set Strict-Transport-Security "max-age=63072000; includeSubDomains"

  3. Restart Apache with systemctl restart apache2

IMPORTANT: If you enable HSTS while using the default SSL certificate generated by Uyuni, or a self-signed certificate, some browsers will refuse to connect using HTTPS unless the CA used to sign such certificates is trusted by the browser. If you are using the SSL certificate generated by Uyuni, you can trust it at the servers by using the file located at `http://<UYUNI-PROXY-HOSTNAME>/pub/RHN-ORG-TRUSTED-SSL-CERT

Technology Preview: Containerized SUSE Manager Proxy and Retail Branch Server

Starting with Uyuni 2022.04, it will be possible to run the Uyuni proxy and Retail branch server also in containers. This could be very helpful in scenarios where adding new virtual machines is not feasible for some reason.

Additionally, the ability to run Uyuni Proxy and Retail branch servers in containers make it more flexible to run them anywhere without worrying about the underlying OS, while also making it possible to get the advantage of Kubernetes offerings like HA.

Version 2022.03

Unsupported products
  • Red Hat Enterprise Linux 6

  • SUSE Linux Enterprise Server Expanded Support 6

  • Oracle Linux 6

  • CentOS 6

  • CentOS 8

  • Ubuntu 16.04

We highly encourage you to migrate your workload to a newer version of each distribution, or to an alternative distribution that is still supported, so you can continue managing your infrastructure with Uyuni.

Please note that we will not break things on purpose for these unsupported products, and there is a possibility that they could still continue to work. But if things break, there will not be any support provided, not even on a best-effort basis, unless someone from the community can step in.

Version 2022.02

Prometheus 2.32.1

Uyuni 2022.02 updates Prometheus from version 2.27.1 to 2.32.1.

The new version contains some breaking changes that need to be addressed after the Uyuni Server is updated.

Breaking changes:

  • Uyuni Service Discovery: The configuration and the returned set of meta labels have changed. Please check the upstream documentation for more details.

  • As a consequence all users with existing monitoring setup must reapply the highstate on the monitoring server(s).

Important changes:

  • Introduced generic HTTP-based service discovery.

  • New expression editor with advanced autocompletion, inline linting, and syntax highlighting.

  • Discovering Kubernetes API servers using a kubeconfig file.

  • Faster server restart times via snapshotting.

  • Controlling scrape intervals and timeouts via relabeling.

Check the upstream changelog for more details on what has changed.

Version 2022.01

Change proxy used for clients from the WebUI

It is now possible to change the proxy used by an Uyuni client using the WebUI.

This can be done from the Connection tab at the Details tab for any Salt client, using the new link Change to change the connection type.

Using System Set Manager is supported as well, and can be done from the Misc tab, and then Proxy tab.

NOTE: Changing the connection for a Proxy to move it, is not supported at this moment. The Connectiontab will not show the Change link for proxies.

Version 2021.12

Salt as a Bundle

Salt Bundle is a single package called venv-salt-minion containing the Salt Minion, Python and all Python modules. It is exactly the same version and codebase for the current salt-minion RPM package.

The Salt Bundle can be used on systems that already run another Salt Minion, that do not meet Salt’s requirements or already provide a newer salt version that is used instead of the version provided by Uyuni.

Starting with Uyuni 2021.12, Uyuni is able to bootstrap systems with Salt Bundle for all the supported operating systems.

On bootstrapping new proxies the Salt Bundle package will be used instead of salt-minion, if the package venv-salt-minion is present in the bootstrap repo.

Proxies already registered will not be changed, but can be switched to Salt Bundle with applying the state util.mgr_switch_to_venv_minion to them.

Prometheus Blackbox exporter

Uyuni 2021.12 comes with the Blackbox exporter, which allows blackbox probing of endpoints over HTTP, HTTPS, DNS, TCP, and ICMP. It needs to be installed next to the Prometheus server and not on the clients. Prometheus formula has been extended to configure the Blackbox exporter.

The package prometheus-blackbox_exporter has been added as recommended for the Proxy.


One of the limitations of the current formulas is that they are listed against every client, even if the supported packages are not available for that OS version or service pack.

While we are continuously focused on improving the formulas, for now, starting with the monitoring formulas it will be mentioned in documentation if applying those formulas would actually work in the case of a particular client.

In 2021.09, we made the Prometheus package available for Uyuni Proxy and Retail Branch Server but that is not the case with Grafana.

  • Prometheus is available for the client tools for SLE 12, SLE 15, and openSUSE 15 Uyuni Proxies or Retail Branch Servers

  • Grafana is available for the client tools for SLE 12, SLE 15, openSUSE15

New product enabled
  • SUSE Linux Enterprise Server 15 SP2 LTSS

CentOS 8 End of Life

CentOS 8 will be End of Life on December 31st, 2021. Uyuni support for this product will end as well.

Please refer to support section for more information.

Future deprecation of the traditional stack

With Uyuni 2021.12, we announced the future deprecation of the Traditional client tools.

Uyuni 2022.06 is the last release that supportes them.

Starting with Uyuni 2022.08, the traditional client tools will be deprecated as we will start removing the code to support them at some point after the summer.

Do not use traditional for any new deployments of clients or proxies, and start migrating your traditional clients to Salt.

Installing the Proxy

Installation of Uyuni Proxy is done via the Uyuni Server web interface.

See the Installation/Upgrade guide for step-by-step instructions on how to install and configure the Uyuni Proxy.

Update from previous versions of Uyuni Proxy

When updating, always start with the server first and then continue with the proxies.

See the Installation/Upgrade guide for detailed instructions on how to upgrade.

  • If you are upgrading from 2022.05 or earlier (at least 2021.06): You will need to follow the "Installation/Upgrade Guide > Upgrade > Upgrade the Proxy" > "Proxy - Major Upgrade" section.

  • If you are updating from 2022.06 or newer: You will need to follow the "Installation/Upgrade Guide > Upgrade > Upgrade the Proxy" > "Proxy - Minor Upgrade" section.

  • Migrating from versions older than 2022.06 is possible only with a proxy replacement, as described at the documentation.

Known Issues

Single Sign On, API and CLI tools

Single Sign On can be used to authenticate in the Web UI but not with the API or CLI tools. This will be fixed in a future release of Uyuni.
