EuroLinux 8 Jump Start

This document contains the necessary information to set up your first EuroLinux 8 installation.

System Requirements

x86_64 (64 bit AMD/Intel architecture)

Minimal and recommended requirements are following:

Resource Absolute minimal requirements for cloud deployment Minimal Recommended
Logical CPU 1 1 1
RAM 768MB or 512MB with swap space 1 GB 1.5 GB per logical CPU
Storage 5 GB (excluding swap) 10GB 20GB

Logical CPU means Physical CPU (including Hyper-Threading) or vCPU (virtual CPU).


It might be impossible to install EuroLinux on a system that does not meet recommended requirements.

aarch64 (64 bit ARM architecture)

Minimal and recommended requirements are following:

Resource Absolute minimal requirements for cloud deployment Minimal Recommended
Logical CPU 1 1 1
RAM 1 GB or 512MB with swap space 2 GB 2 GB per logical CPU
Storage 5GB 10GB 20GB

About absolute minimums for cloud deployment

During our internal testing, we were able to boot and use very basic and already installed services on Virtual Machine with only 256 MB of RAM. However, without additional memory or at least swap space available, things like updating the system will result in actions of Kernel Out of Memory (OOM) Killer.

You can try it yourself with EuroLinux Vagrant boxes and following Vagrantfile:

Vagrant.configure("2") do |config| = "eurolinux-vagrant/eurolinux-8"

  # Explicitly disable vbguest because we are using rsync
  if Vagrant.has_plugin?("vagrant-vbguest")
      config.vbguest.auto_update = false

  config.vm.provider "virtualbox" do |vb|
    vb.memory = "256"
    vb.cpus = 1
  config.vm.provider "libvirt" do |vb|
    vb.memory = "256"
    vb.cpus = 1

It's also possible to install EuroLinux on less than 5 GB of space, but it also requires extra attention.

All absolute minimums for cloud deployments described above are not officially supported by EuroLinux.

Secure boot

At the moment, EuroLinux does not support secure boot. The full secure boot support is planned at the end of Q1/beginning of Q2 2022.

How to install EuroLinux 8 from ISO

Where can you obtain ISO?

We distribute EuroLinux in a responsible open core model. Because of that, you might download EuroLinux from different sources. The two primary sources are:

The only difference is that Customer Portal keeps older versions, when CDN, that is used for mirroring, keeps only two of the latest ISOs for each version to save space (single EuroLinux AppStream ISO might take up to 10 GB).

If you are running a huge deployment, you might consider setting up your own mirror and download ISOs from Intranet.

How to check ISO integrity

During download, many things can happen - from a network or sending host failure to single-bit error. To check if ISO is undamaged, there are two mechanisms in place.

  • For each EuroLinux ISO there's a file with its checksums and appropriate digest algorithms. Its name says, which algorithm was used to calculate the cryptographic digest. For example, you can browse and read the sha1sums.txt file.

When the ISO download is completed, you can invoke the sha1sum command on the ISO file and check if checksums match.

[Alex@SpaceShipEL8 Downloads]$ sha1sum EL-8.3-x86_64-20210624-appstream.iso 
6a8abaaebe288553ec8568bd9de3f5fda5f1ddb5  EL-8.3-x86_64-20210624-appstream.iso
  • The second mechanism for checking ISO integrity is built-in inside the installer itself. When you start the installation, use the Test this media & install EuroLinux 8 entry:

Installation 1

After booting up, the ISO checking process will start.

Installation 2

Installation with GUI

Because even a minimal installation uses a GUI the whole process is simple and straightforward. EuroLinux 8, as well as previous versions, uses Anaconda installer that clearly informs the user what needs to be done in order to install the system.

First, you have to choose the language that will be used during installation: Installation 3

After configuring the installer language you should see a menu similar to:

Installation 2

Anaconda installer LOCALIZATION section:

  • Keyboard - this section allows you to setup keyboard layouts, including the default keyboard layout, additional layouts and key combination to switch between them.
  • Language support - additional languages packages that should be installed.
  • Time & Date - configure the date, time zone, enable NTP and NTP servers.

Anaconda installer SOFTWARE section:

Configuring source of the installation

Here you might configure the source of your installation. By default, the system installs from the ISO image itself. This is one of the officially supported ways to install EuroLinux.

If you enable a NIC (Network Interface Card) in the Network installer section, you might add additional EuroLinux repositories and/or other repositories. If you add EuroLinux repositories, the installer will automatically download newer version of the packages.

'certify-' prefix

Since EuroLinux 8.6 the 'certify-' prefixes in repo URLs and names are no longer used. These names and URLs were used before we started distributing our system in the open core model. These URLs are and will be kept as the symbolic link for backward compatibility. They can be used in some older parts of the documentation.

EuroLinux 8 repositories:

  • URL:$basearch/BaseOS/os
    Name: BaseOSProd
  • URL:$basearch/AppStream/os
    Name: AppStreamProd
  • URL:$basearch/PowerTools/os
    Name: PowerToolsProd

For EuroLinux 8 beta:

  • URL:$basearch/beta-BaseOS/os
    Name: BaseOSBeta
  • URL:$basearch/beta-AppStream/os
    Name: AppStreamBeta
  • URL:$basearch/beta-PowerTools/os
    Name: PowerToolsBeta

Limited support.

Hybrid network installation from both ISO and public repositories is not our primary goal in the QA process. Packages in EuroLinux repositories are regularly updated, and it might be impossible to install a system from an external source. Depending on the state of the upstream, we might not fix a potential issue.

Below you can see an example configuration that was used to install a system:

Adding additional repositories

After changing the installation source, you will have to confirm Software Selection.

Software Selection

Software Selection allows you to customize which packages will be installed. You might choose from base environment groups like Server with GUI, Workstation or Minimal. You can also install additional package groups.

Software selection section

Anaconda installer SYSTEM section:

  • Installation selection allows choosing on which disk the system will be installed. If you want to have a fully encrypted system, you should enable encryption in this step.
  • KDUMP allows choosing if KDUMP (Kernel crash dump collection mechanism) should be enabled.
  • Network & Hostname - you can configure your system networking here
  • Security policy - you can setup an additional openscap policy here

Anaconda installer USER SETTINGS section:

  • Root Password - by default, the root user is disabled. If a user is created in User Creation section, the root account can stay disabled
  • User Creation section allows creating a regular user in the system. If the Make this user administrator option is checked, the root account can be disabled.

After applying all the necessary changes, the installation can be started with the "Begin Installation" button.

You need at least the following partitions.

  • /boot for Linux kernel and init ramdisks - 1GB
  • / (root partition) - at least 10 GB (a very minimal system might use as little as 2GB - but it requires extra attention and is not officially supported by EuroLinux)

For UEFI, an EFI system partition is also required.

  • /boot/efi - at least 100MB

If your storage allows it, the following partitions are also highly recommended:

  • swap - 1GB or more depending on the system RAM and workload. Swap is also required for hibernation. Depending on the workload of the system, it should be at least as spacious as system RAM.
  • /home - at least 1GB - but in most cases, if / can be as big as 80GB, then /home/ usually takes the rest of the free space

Installing EuroLinux in basic graphic mode

Suppose there is a problem loading/running your graphics card driver (it might results in a black screen/error message or graphical artifacts). It's possible to install EuroLinux in basic graphics mode.

To do so, choose Troubleshooting on the welcome menu, and then Install EuroLinux 8 in basic graphics mode.

From this point the process is identical to a standard installation with GUI.

Installing EuroLinux in text mode

To install EuroLinux in text mode:

  • Boot EuroLinux ISO
  • Press Esc to stop installation options selection timeout
  • Press Tab
  • Add inst.text to the end of the kernel boot command line
  • Press Enter

Text Install 1

Before running the installation you have to provide all the necessary information (represented as ! in selection). It's a good idea to refresh the menu with R+Enter command shortly after the installer started.

Text Install 2

After customization you are ready to start your installation.

Text Install 3

Other possibilities

EuroLinux can also be installed in the following manner:

  • Automated installation with a kickstart file.
  • Installation with PXE
  • Installation via VNC

Please consult upstream documentation about these topics.

Using EuroLinux

From this point, you can use EuroLinux as any other RHELâ„¢ based distribution.

Submitting a Request for Change

We truly care. If there is something that you believe could/should be changed/improved in the EuroLinux distribution and does not break compatibility with the upstream project, then drop us the issue on GitHub! All contributors are extremely welcome.

EuroLinux Distro Bugs and RFC

Submitting a Bug report

We decided that submitting bug reports should not involve registration into some nasty miserable software. At the very same time, we know that most open-source developers have GitHub profiles. This choice makes the decision making and work as transparent as possible. That's why we decided to use it as the primary way to submit bugs.

EuroLinux Distro Bugs and RFC

This repository allows you to stay in direct contact with EuroLinux developers.
