LibraZiK-3 Installation - method 1
(Version française / French version)


LibraZiK-3 installation logo - click to enlarge Here we will install a LibraZiK-3 Audio Studio either on an empty hard disk 1) or add it to an already installed Debian Buster.

Warning: LibraZiK-3 may not work properly if you have other repositories installed.
This tutorial was reviewed in December 2019 on LibraZiK-3.

If you already have a Debian Buster installed, you can jump directly to this paragraph.

Otherwise, please continue reading and we will install it.

You'll need:

  1. get a Debian installation image (Buster version)
  2. burn it on a CD, DVD or write it on a USB key
  3. then, we're going to install a basic Debian system
  4. then, we'll install the LibraZiK-3 environment
  5. and then we'll go in and make the final setups

These different steps are described below.

Getting an ISO image of Debian

We will use a “Debian Internet Installation” base. So you will need an active internet connection during the actual installation.

One of the advantages of this method is that your system will be completely up to date at the time of installation because the software will be downloaded in its most recent versions from the Debian repositories.

So we will retrieve an ISO image of the installation from the internet (called “netinst”). This image contains everything you need to install debian on 64-bit or 32-bit systems. It can be found here: and has a name like: debian-10.X.Y-amd64-i386-netinst.iso (about 616 MB).

If you want to be resource-efficient, you can download an ISO image only for a 64-bit system or for a 32-bit system.

To find out if you need a 64-bit or 32-bit system, please see the FAQ question: Do I need a 64_or_32_bit system? (in French).

Once you know which system you are going to install (64-bit or 32-bit), go to the Debian website where you will download the netinstal CD image for amd64 (64-bit) or for i386 (32-bit), which you will find in the directories:

If you need an installation for a machine requiring non-free drivers (the most common case is an installation on a laptop requiring a non-free driver to run the WiFi), you can find an unofficial image here: and

Burning/writing the Debian ISO image

If you are using a CD or DVD for installation

Burn this ISO image to a CD or DVD using your usual software.

If you are using a USB key for installation

Be careful, everything on your USB flash drive will be destroyed - so be sure :
  • of the target partition to be used,
  • to have a saved copy of what was on your key.

To write this image on a USB key, follow these few steps:

  1. In a terminal, run the command : watch "dmesg | tail" (as administrator account).
  2. Then plug your USB key on your computer, you will see the writings on your terminal changing. It's your linux® kernel which is telling you that it discovers a new device and what it does with it.
  3. Find out where your USB key is located. For example : sdb: sdb1.
  4. Then, in another terminal tab (do: Terminal menu → Open a tab ), the magic command to write the ISO on the USB key and make it a bootable key is: cp /path/to/your/file.iso /dev/sdX (as administrator account) by replacing the “X” of /dev/sdX by the letter corresponding to the location of your USB key (in the example above: /dev/sdb)
  5. Once the copy is made and when the terminal gives you the hand back, run the command sync which ensures that everything is written and synchronized, and that there is nothing more being written to the key.
  6. Unmount your key cleanly.
  7. Close the terminal window.
  8. Your flash drive is ready.
The ISO image should be copied to the entire device, not just one of its partitions. For example: /dev/sdb and not /dev/sdb1.

Installing a Debian base

If you have a firewire audio interface, it must be unplugged during installation.
If needed, the official debian installation manuals can be found here:
The procedure below assumes that only LibraZiK-3 will be installed on your machine. In the case of a multi-system machine, you will adapt accordingly.
  • Start the computer with the CD or DVD in the drive, or with the USB key plugged into your machine.
On some machines, it is sometimes necessary to press a button when turning it on to be able to boot from a CD, DVD, or USB key.
  • Choose :
    • “Graphical Install” for a 64-bit system,
    • “32-bit install options” then “Graphical install (32-bit)” for a 32-bit system.
If that doesn't work, try “Install”.
  • Choose :
    • “What you need - What you need”
    • “The country your in”
    • “The keyboard type you're using”
  • Network configuration if needed
  • Choose the machine name
  • Choose the domain name
  • Choose a password for the administrator account
  • Choose the user account name
  • Choose the user account ID
  • Choose the user account password
  • Choose “Assisted - use the whole disk”
  • Select the hard drive on which your system will be installed
  • Choose “All in one partition (recommended for beginners)”
  • Select “Finish partitioning and apply changes”
  • Select “YES”
The basic system is then installed from the support (USB key). It should be quite fast..
  • Choose a mirror : choose “the country you're in” then, advice is to choose either :
    • “” which selects the fastest mirror to respond (preferred choice if possible),
    • a mirror geographically close to you.
  • proxy http: → leave it blank, unless you're behind a proxy
The rest of the system is installed from the web and it will take more time depending on the quality of the internet connection.
  • Statistical study, choose “YES”
  • Choose the MATE desktop environment in addition to the other pre-selected items
The rest of the system is installed from the web and it will take more time depending on the quality of the internet connection.
  • Install GRUB on the boot sector: “YES”
  • Choose the hard disk on which to install GRUB
  • Remove the support 2), then “CONTINUE”.

…the computer will reboot.

Installing the LibraZiK-3 environment

We will see here how to integrate the LibraZiK-3 audio studio to an already installed Debian Buster. You will need a Debian Buster system (64 or 32 bits) already installed with the MATE desktop environment, and a working internet connection.

Here, we will install the LibraZiK-3 environment before we can enter it.

  • Login with your user account
  • Menu → System → Administration → Synaptic package manager
    • Install the gdebi package 3)
    • Once the software is installed, close Synaptic
  • Menu → Applications → Internet → Firefox ESR
  • Once downloaded, install the librazik-keyring package by right-clicking on it then “Open with GDebi Package Installer”
  • Do the same with the librazik-apt package
Once installed, you can put these 2 packages in the trash can.
  • Reopen the Synaptic Package Manager
    • Click on “Reload
    • Here you might get an error of the type: Synaptic : erreur de doublon - cliquer pour agrandirThis error is benign 4). If you want to correct it right away, go read this page (in French). Otherwise, you can continue by clicking “Close”.
  • Then “Reload” again Synaptic
  • Do a search on “librazik-”
    • Install the meta-packages according to your needs while accepting automatic proposals of packages to be installed or uninstalled.
If you don't know much about it and just want to install a complete LibraZiK-3, install the meta-packages : librazik-menu, librazik-base-all, librazik-mate-all, librazik-optimisations-all et librazik-theme-all, and keep reading this page until the end, as well as the links (“Configuration” in particular) to which it refers.

For more information, take the time to read this page (in French) to understand what each of these meta-packages do. The librazik-optimizations-all package is particularly recommended.
  • → You may be asked this:
    • Do you need to enable real-time process priority management? [yes/no]
    • Enter yes and then the ↵ Enter.
Note that you have to scroll down the frame to see this question.
  • Once you've installed the software, do a update
  • Close Synaptic
  • Finally, close the session and log in again so that some things (menu, part of the theme,…) can be taken into account

Configurations of your LibraZiK-3 system

To finish installing your LibraZiK-3 audio studio, you will want to add some configurations to your system.
