On November 30, 2022, we released version 9.1 of the EuroLinux operating system. It is compatible with the latest upstream version. This release focuses on updating containerization and cloud tools. EuroLinux 9.1 introduces Keylime, a tool for remote machine authentication that uses Trusted Platform Module (TPM) technology. The Linux kernel has been updated to version 5.14.0-162.
In EuroLinux 9.1, the SELinux package has been upgraded to version 3.4. Among the most noticeable changes are:
- improved relabeling performance with parallel relabeling
- new policy tools in the libsepol-utils package
- SHA-256 support in the semodule tool.
Since version 8.3, the EuroLinux operating system is offered in an Open Core model - both as a paid subscription and free of charge. Customers and the community get access to the software at the same time, in the same version and in the same repositories.
The paid subscription additionally provides:
- manufacturer's technical support
- access to errata files
- access to additional intermediate packages
- the possibility to influence product development.
Supported system versions
We provide all the officially supported versions of the Enterprise Linux family of systems:
- 9.1 - fully supported until 30 June 2032
- 8.7 - fully supported until 30 June 2029
- 7.9 fully supported until 31 July 2024
- 6.10 the system is supported by EuroELS (Extended Life Support – individual subscription).
EuroLinux version 9 and 8 is the only system to officially provide entire build trees and so-called buildroots. This streamlines software development for developers and advanced users.
Example dnf/yum configuration for use in building packages:

EuroLinux 9 and 8 also provide packages in the i686 architecture for building 32-bit applications. These allow you to create environments that require 32-bit libraries to ensure backward compatibility. An example of a yum.conf configuration used in a tool such as mock:

Forks and dedicated EuroLinux versions
As an organization we have been supporting various systems from the Enterprise Linux family since the very beginning. Since version 8 we have gained new abilities - in addition to the basic system we have the ease of building and maintaining dedicated systems that are forks of EuroLinux and special purpose Linux distributions (including custom built systems). With each release EuroLinux is tested many times. We check subsystems and build artifacts, that is, components of the system. All this is done so that creating a fork as well as a dedicated distribution is as easy as possible and gives the expected, reproducible results.
Universal migration scripts
One of the important elements of our offer are universal migration scripts. Currently they support migration to EuroLinux from Enterprise systems in the following versions:
- Red Hat Enterprise Linux 7, 8, 9
- AlmaLinux 8, 9
- CentOS 7, 8
- Oracle Linux 7, 8, 9
- Rocky Linux 8, 9
The scripts also offer experimental support for:
- CentOS 9 Stream.
The migration scripts along with a description of the migration process can be found in the Migration Scripts GitHub repository. The latest versions of the scripts include enhancements to preserve packages from other distributions (however, this may imply the use of third-party software). We have described the migration process here. There is also a video tutorial there.
Upgrade from a lower version of Enterprise Linux to a higher version
EuroLinux is part of the ELevate Project. The project is currently enabling the transition from CentOS 7 to EuroLinux 8 and is under constant development. Instructions for using the tool will appear soon on our website.
Additional modules (Add-On) in each system
EuroLinux is a complete solution, including as a standard the modules that are available at additional cost in other distributions. They extend the functionality of the system and increase its technical value. Among them one can distinguish: High Availability and Resilient Storage. In the near future we will also make the NFV and RT repositories available.
The software, like any tool, is of little use without people who know how to use it properly. That is why we also offer authorized training in the administration of Enterprise Linux systems at various levels of advancement:
- Enterprise Linux System Administration I
- Enterprise Linux System Administration II
- Enterprise Linux Real Engineer
- Enterprise Linux Ansible Engineer.
Open documentation and JumpStart
Open documentation is available for EuroLinux. We wanted to be as transparent as possible and to be able to involve the community, which makes the following possible:
- a repeatable documentation process - any user can build it and run it locally
- submitting ideas - our engineers will be happy to take on topics that the community feels are important and need clarification
- submitting fixes - anyone can submit their own fixes to the documentation
- submitting your own documentation to become part of the EuroLinux documentation.
The open source documentation is available at docs.euro-linux.com and hosted using the GitHub Pages mechanism. This is a new project, so the documentation is being gradually added.
New Vagrant boxes
Vagrant boxes for VirtualBox, libvirt and VMware Workstation are available at the following address:
All the available versions can be found here.
The complete stack – more than a system
In addition to the operating system, we offer a number of other products. What is important, they can run on any system from the Enterprise Linux family and selected SUSE systems. All of them are based on Open Source projects and together form a useful technology stack. These are:
- EuroAP – Java application server compatible with JBoss® EAP
- EuroDB – database platform based on PostgreSQL
- EuroMan – Linux update management platform
- EuroStorage – mass storage platform (SDS)
- EuroIQ – hybrid cloud management platform
- EuroTower – an automation management platform with Ansible
- EuroSSO – complete Single Sign-On backend.
EuroLinux Gaia 3.0 – build your own Linux platform
EuroLinux Gaia is a proprietary tool that allows you to build (compile) an operating system yourself from source files in your own customer infrastructure. EuroLinux 9 x86_64 was built using the Gaia 3.0 stack, and we are currently building EuroLinux 9 ARM64 (aarch64) with an updated rebuild stack. Improvements to EuroLinux Gaia 3.0 include.:
- clear web interface with LDAP/IPA login support
- simple REST API using YAML
- administration panel
- role division - builder, quality engineer, publisher
- improved resource usage by using parallel builds
- automation of log and artifact centralization
- creation of external repositories according to rules
- running the agent on any user with appropriate permissions
- new gaia-build console interface that can also invoke builds on the local system.
With the EuroLinux Gaia solution the customer receives:
- EuroLinux Gaia build system
- software comparison system with test oracle
- Battery Repositories, which are packages not included in the distribution, necessary for building it
- internal EuroLinux Gaia documentation for building the system
- direct support (on-site, telephone, e-mail) from a EuroLinux Release Engineer
- Golden Key subscription.
Release Notes are available in open documentation: EuroLinux 9.1 Release Notes
