Chapter 1: Introduction, Philosophy and Preparation of the EnvironmentHome

Ubuntu 24.04 LTS "Noble Numbat" is the banner of modern free computing. Based on Debian, Ubuntu balances end-user accessibility with industrial strength. His story began in 2004, when Mark Shuttleworth founded Canonical with the mission of democratizing Linux. Shuttleworth, a South African private astronaut and businessman, saw in Debian the perfect basis but lacking a predictable life cycle for the common user.

The Ubuntu philosophy is summarized in the concept of "Humanity towards others." This means that the software must be free, accessible in the native language of the user and functional without the need for an exhaustive technical configuration by the end user. However, under that layer of simplicity, Ubuntu is a highly complex and optimized system for the cloud and professional desktop.

1.1 The Launch Ecosystem: LTS vs Interim

The Ubuntu development model is one of the most rigorous in the industry. The versionsLTS (Long Term Support)they are launched every two years (in April of the years pairs) and have a base support of 5 years, which can be extended to 12 years through services like Ubuntu Pro. This makes them the preferred option for critical infrastructure and production servers.

On the other hand, theInterim Releasesare launched every six months and have a short life cycle of 9 months. These versions serve as a technological battlefield where Canonical introduces new versions of the kernel, GNOME and base libraries, preparing the ground for the next great LTS.

1.2 Official flavors: The Diversity of Ubuntu

Ubuntu is not just GNOME. Canonical recognizes several official "flavors" that share the same repository base but offer different desktop environments (DE):

• Kubuntu:The power of KDE Plasma.
• Xubuntu:Light with XFCE for old hardware.
• Lubuntu:Maximum efficiency with LXQt.
• Ubuntu Budgie / MATE / Unity:Aesthetic and functional alternatives.

In the architecture of Ubuntu, the Introduction, Philosophy and Environmental Preparation component is integrated by using hooks (hooks) of the system. This allows security updates to spread in an atomic way. The technical implementation follows the guidelines of the Linux Foundation and the LSB (Linux Standard Base) standards. It is essential to understand that Ubuntu is not a collection of random packages, but a coherent ecosystem where each C library and each kernel header has been audited to ensure binary compatibility (ABI) throughout the LTS life cycle.

By analyzing the abstraction layer, we note that Ubuntu prefers the use of declarative interfaces. This is manifested in tools such as Netplan or AppArmor configurations, where the administrator defines the "desired state" and the system is in charge of translating it to the low-level rules ofiptables, nftablesor the kernel parameters in/sys/class. This design philosophy reduces the probability of human errors and facilitates the creation of automation scripts using Ansible or Terraform, pillars of infrastructure as a modern code (IAC).

To optimize performance, the Ubuntu 24.04 kernel includes latency optimizations (preemption) that improve desktop experience without compromising the performance of the server under high concurrence. The EEVDF process planner is responsible for distributing tasks among the CPU nuclei efficiently, prioritizing applications that require an immediate user response, such as the PipeWire audio server or the GNOME graphic composer.

Chapter 2: Base Installation - Subiquity and Systems ArchitectureHome

The Ubuntu 24.04 installation uses the new installer based onFlutter, which offers a modern and fluid experience. However, the underlying engine remainsSubiquity, an industrial-grade tool capable of managing mass deployments.

2.1 Technical preparation of the Hardware

Before we start, we must set the base plate. In modern systems, theUEFIIt's mandatory. Unlike Arch, Ubuntu supports nativelySecure Boot, which allows the kernel to be loaded under a reliable digital signature, protecting the system against bootkits at firmware level.

# Verificar si estamos en modo UEFI desde el medio Live
[ -d /sys/firmware/efi ] && echo "UEFI Mode active"

2.2 Storage Architectures: LVM, LUKS and ZFS

Ubuntu allows disk configurations that in other disters require complex manual steps:

• LVM (Logical Volume Manager):It allows to resize hot partitions and create volume snapshots.
• LUKS (Linux Unified Key Setup):Full disk encryption with AES-256. Essential for professional laptops.
• ZFS on Root:Although experimental, Ubuntu offers native support for ZFS, allowing self-repair of integrated data and snapshots with the package manager.

The manual partition ("Something else") gives us absolute control over the scheme. We recommend a 1GB '/ boot / efi' partition, at least 60GB '/' root partition and the rest for '/ home', providing future version updates without data loss.

Chapter 3: Post-System Installation and ConfigurationHome

After the first start, Ubuntu presents a clean desktop, but an administrator must configure the system for performance and safety. The first step is to masterAPT (Advanced Package Tool).

3.1 Anatomy of Ubuntu Repositories

Ubuntu divides its software into four main components according to its support and licensing:

• Main:Free software officially supported by Canonical.
• Restricted:Owner controllers (NVIDIA, etc.) supported.
• Unify:Free software maintained by the community (the vast majority of packages).
• Multivate:Software not free or with legal restrictions.

# Actualización integral del sistema
sudo apt update && sudo apt full-upgrade -y
# Limpieza de paquetes huérfanos
sudo apt autoremove --purge

3.2 Netplan: Declarative Network Settings

In Ubuntu, we no longer edit/etc/network/interfaces. The network is managed byNetplan, which uses YAML files in/etc/netplan/. This allows a consistent configuration in both desks (using NetworkManager) and servers (using systemd-networkd).

# Ejemplo de IP estática en /etc/netplan/01-netcfg.yaml
network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
      addresses: [192.168.1.50/24]
      routes:
        - to: default

In the Ubuntu architecture, the Post- System Installation and Configuration component is integrated by using system hooks. This allows security updates to spread in an atomic way. The technical implementation follows the guidelines of the Linux Foundation and the LSB (Linux Standard Base) standards. It is essential to understand that Ubuntu is not a collection of random packages, but a coherent ecosystem where each C library and each kernel header has been audited to ensure binary compatibility (ABI) throughout the LTS life cycle.

By analyzing the abstraction layer, we note that Ubuntu prefers the use of declarative interfaces. This is manifested in tools such as Netplan or AppArmor configurations, where the administrator defines the "desired state" and the system is in charge of translating it to the low-level rules ofiptables, nftablesor the kernel parameters in/sys/class. This design philosophy reduces the probability of human errors and facilitates the creation of automation scripts using Ansible or Terraform, pillars of infrastructure as a modern code (IAC).

To optimize performance, the Ubuntu 24.04 kernel includes latency optimizations (preemption) that improve desktop experience without compromising the performance of the server under high concurrence. The EEVDF process planner is responsible for distributing tasks among the CPU nuclei efficiently, prioritizing applications that require an immediate user response, such as the PipeWire audio server or the GNOME graphic composer.

Chapter 4: Advanced Networks and Audio ArchitectureHome

Modern connectivity in Ubuntu is based onSystemd-resolvedfor DNS management. This allows to implement advanced protocols such asDNS, improving privacy by encryption of name resolution requests.

4.1 Audio Architecture: The PipeWire Age

Ubuntu 24.04 consolidates transition toPipeWire, the successor of PulseAudio and JACK. PipeWire offers a very low latency and superior management of Bluetooth devices. Thanks toWirePlumber, the session manager, the applications can connect dynamically to different audio inputs and outputs with extreme fidelity.

# Comprobar el estado de PipeWire
pactl info | grep "Server Name"
# Ajustar el volumen del dispositivo por defecto mediante wpctl
wpctl set-volume @DEFAULT_AUDIO_SINK@ 0.5

Chapter 5: Package Management: APT, Snap and FlatpakHome

Ubuntu offers the richest package ecosystem in Linux, combining the traditional.debwith the modernSnaps.

5.1 Snaps: Application Containers

Snaps are compressed packages that include all their dependencies. They run isolated from the system by means ofAppArmor, which is a massive safety layer. Although criticized for its start speed, they are the official form of Canonical to distribute software always updated as VS Code, Firefox or Docker.

# Instalar Firefox vía Snap (por defecto en Ubuntu)
sudo snap install firefox
# Ver los canales disponibles (edge, beta, stable)
snap info firefox

5.2 PPAs and Flatpays

For software not present in the repositories, Ubuntu has thePPAs (Personal Package Archives)from Launchpad. However, its use must be careful to avoid "hell of dependencies." Alternatively, many users choose toFlatpakand the Flathub store for third-party desktop applications.

In the Ubuntu architecture, the Advanced Personalization and 'Rancing' component in Ubuntu is integrated through the use of system hooks. This allows security updates to spread in an atomic way. The technical implementation follows the guidelines of the Linux Foundation and the LSB (Linux Standard Base) standards. It is essential to understand that Ubuntu is not a collection of random packages, but a coherent ecosystem where each C library and each kernel header has been audited to ensure binary compatibility (ABI) throughout the LTS life cycle.

By analyzing the abstraction layer, we note that Ubuntu prefers the use of declarative interfaces. This is manifested in tools such as Netplan or AppArmor configurations, where the administrator defines the "desired state" and the system is in charge of translating it to the low-level rules ofiptables, nftablesor the kernel parameters in/sys/class. This design philosophy reduces the probability of human errors and facilitates the creation of automation scripts using Ansible or Terraform, pillars of infrastructure as a modern code (IAC).

Chapter 10: Systemd - Orchestra and AutomationHome

Ubuntu is orchestrated entirely bysystemd. This manager not only starts the PC, but monitors each service and timer.

10.1 Unit and Timer Management

TheSystemd Timersare the modern replacement of Cron. They offer more precision and are integrated with the system log. We can create our own service units in/etc/systemd/system/to automate heavy tasks or local deployments.

# Analizar qué servicios ralentizan el arranque
systemd-analyze blame
# Ver el árbol de dependencias de un servicio
systemctl list-dependencies ssh

10.2 cgroups v2 and Resource Control

Ubuntu usescgroups v2to limit the use of CPU and RAM of processes. This ensures that a background process (such as a heavy compilation) does not leave the desktop blocked due to lack of resources.

Chapter 11: Optimization of Hardware and PerformanceHome

For Ubuntu to fly, we must make fine adjustments to the memory management and the system core.

11.1 zRAM: Memory Compression

In teams with little RAM,zRAMcreates a compressed block in the memory that acts as ultra-fast swap. This prevents the use of the slow hard drive (thrashing) and improves the system response under heavy load.

sudo apt install zram-config
# Ajustar el swappiness a un valor bajo (ej. 10) para priorizar RAM física
sudo sysctl vm.swappiness=10

The EEVDF process planner is responsible for distributing tasks among the CPU nuclei efficiently, prioritizing applications that require an immediate user response, such as the PipeWire audio server or the GNOME graphic composer.

In the Ubuntu architecture, the component of The Art of Software Development in Ubuntu is integrated through the use of system hooks. This allows security updates to spread in an atomic way. The technical implementation follows the guidelines of the Linux Foundation and the LSB (Linux Standard Base) standards. It is essential to understand that Ubuntu is not a collection of random packages, but a coherent ecosystem where each C library and each kernel header has been audited to ensure binary compatibility (ABI) throughout the LTS life cycle.

By analyzing the abstraction layer, we note that Ubuntu prefers the use of declarative interfaces. This is manifested in tools such as Netplan or AppArmor configurations, where the administrator defines the "desired state" and the system is in charge of translating it to the low-level rules ofiptables, nftablesor the kernel parameters in/sys/class.
