1. What Is RakuOS? – A Quick Overview

RakuOS is an open‑source, community‑driven Linux distribution that blends a rolling‑release model with a curated set of up‑to‑date packages. Built on a modern kernel (currently 6.8 as of the 2026 release) and the Raku desktop environment, it emphasizes speed, minimalism, and a developer‑friendly toolbox.

Key selling points for 2026:

• Immutable base system with optional mutable layers (great for reproducible environments).
• ZFS‑ready out of the box, complete with snapshot management tools.
• Flatpak and AppImage support baked in, delivering the latest GUI applications without dependency hell.
• Integrated AI‑assisted package search via the newly introduced RakuAI index.

If you’re a developer, power user, or just someone who appreciates a sleek, responsive desktop, RakuOS has become a compelling alternative to mainstream distros.

2. Why Install RakuOS in 2026?

Bottom line: RakuOS delivers a future‑proof, secure, and developer‑centric environment that’s been polished for modern hardware (think of the latest AMD Ryzen 7000 series, Apple Silicon via virtualization, and ARM‑based laptops).

3. Preparing for the Installation

3.1 System Requirements

Tip: For a buttery‑smooth experience, a solid‑state drive (NVMe preferred) and at least 8 GB of RAM are strongly encouraged.

3.2 Backing Up Existing Data

If you’re installing over an existing OS or planning a dual‑boot, never skip a backup. Recommended options:

• Clone the drive with Clonezilla or dd for a full image.
• Sync important folders to an external HDD/SSD using rsync:
• rsync -avh –progress /home/youruser/ /media/backup_drive/youruser_backup/
• Create a cloud snapshot of critical files (Google Drive, Nextcloud, etc.) for added safety.

3.3 Creating a Live USB

1. Download the ISO
   • Head to the official site: https://downloads.rakuos.org/2026/rakuos-2026-amd64.iso.
   • Verify the checksum (SHA256) to ensure integrity:
   • sha256sum rakuos-2026-amd64.iso
   • # Compare the output with the checksum on the download page.
2. Choose a USB creation tool (depends on your current OS):
   • Windows: Rufus (v4.4 or later).
   • macOS: Balena Etcher or dd via Terminal.
   • Linux: dd, gnome-disks, or Ventoy.
3. Write the ISO (example with dd on Linux/macOS):
4. sudo dd if=rakuos-2026-amd64.iso of=/dev/sdX bs=4M status=progress oflag=sync

Replace /dev/sdX with the correct device (e.g., /dev/sdb). Double‑check you have the right drive; a mistake will erase data.

1. Eject safely and plug the USB into the target machine.

4. Booting Into the RakuOS Live Environment

1. Power on the computer and enter the firmware menu (usually F2, Delete, Esc, or F12).
2. Navigate to the boot order and place the USB drive at the top.
3. Save & exit; the system should restart into the RakuOS Live screen.

You’ll be greeted by a clean desktop with a “Try RakuOS” and “Install RakuOS” button. Select “Try RakuOS” first if you want to test hardware compatibility (Wi‑Fi, GPU drivers, Bluetooth, etc.) before committing.

5. Installation Walkthrough

Once you’re ready, click “Install RakuOS” on the Live desktop. The installer is a polished, wizard‑style GUI – think “Ubuntu Ubiquity” meets “Fedora Anaconda”. Below is a step‑by‑step breakdown of each screen.

5.1 Launching the Installer

• Welcome Screen – Choose your language (affects UI, keyboard layout defaults, and help documentation).
• Click Continue.

5.2 Language & Keyboard Layout

• Language: Choose your preferred language (English (US) is default).
• Keyboard layout: Detect automatically or manually pick from a list.
• Press Next.

5.3 Disk Partitioning Options

RakuOS offers three “out‑of‑the‑box” partitioning schemes:

Recommended “Something else” Configuration (Advanced)

1. Boot mode: Confirm if your firmware is in UEFI or Legacy BIOS. For modern hardware, UEFI is preferred.
2. Create a 300 MiB EFI System Partition (ESP)
   • Type: EFI System Partition
   • Filesystem: FAT32
   • Mount point: /boot/efi
3. Create a 2 GiB /boot partition (optional, but helpful for kernel rollbacks).
   • Filesystem: Ext4 (or Btrfs if you love sub‑volumes).
   • Mount point: /boot
4. Create a root partition
   • Size: ≥30 GiB (more if you plan to install many apps).
   • Filesystem: Btrfs (or ZFS – choose “ZFS on Linux” kernel module).
   • Mount point: /
5. Create a swap partition (or swapfile later).
   • Size: RAM size × 1‑2 (e.g., 8 GiB).
   • Type: Linux swap.

If you want full‑disk encryption, select the “Encrypt the new partition” checkbox for each partition (or create a single encrypted LUKS container that houses the ESP and root). RakuOS will prompt you for a passphrase.

After partitioning, click Next.

5.4 User & Password Setup

• Full name: Your real name (optional).
• Username: Must be lowercase, no spaces.
• Password: Strong password (≥12 characters, mix of upper/lower, numbers, symbols).
• Log in automatically? (Not recommended for laptops in public spaces.)
• Require a password to unlock the screen? – Turn on for added security.

Press Next.

5.5 Selecting Software Packages

RakuOS ships with a modular installer that lets you pick a base environment:

Choose Desktop if you’re new, then tick additional groups you need (Development, Multimedia). The installer will compute download size and confirm.

5.6 Review & Begin Installation

A final summary appears: disk layout, user info, selected packages, network connectivity.

• Network: If you’re online, the installer will download the latest package list from RakuOS mirrors. You can also defer updates to post‑install.

Click Install.

Installation Time: Expect 5‑15 minutes on a modern SSD; slower on HDDs or when downloading many packages.

During this phase, the screen shows a progress bar, logs, and a friendly “Did you know?” tip rotating in the corner (e.g., “RakuOS includes built‑in AI suggestions for shell commands!”).

Once complete, the installer will prompt you to restart. Remove the USB when instructed.

6. First‑Boot Configuration

6.1 Updating the System

Open a terminal (Ctrl + Alt + T) and run:

sudo rakupkg refresh          # Refresh package index

sudo rakupkg upgrade         # Upgrade all installed packages

Alternatively, use the Raku Software Center (GUI) → System → Updates.

6.2 Installing Additional Drivers

RakuOS detects most hardware automatically, but for proprietary GPU drivers:

• NVIDIA:
• sudo rakupkg install nvidia-dkms
• AMD (open-source, usually auto‑loaded).
• Wi‑Fi (e.g., Intel AX210):
• sudo rakupkg install iwlwifi-firmware

Reboot after installing drivers.

6.3 Enabling the Firewall & Security Tools

RakuOS ships with UTFT (User‑friendly firewall tool) and AppArmor profiles.

sudo systemctl enable –now utft.service

sudo systemctl enable –now apparmor.service

Open UTFT from the menu → toggle “Enable firewall”.

7. Post‑Installation Tweaks & Recommended Apps

Install them in one swoop:

sudo rakupkg install zsh powerline-fonts zsh-autosuggestions \

libreoffice-fresh krita obs-studio \

git docker vscode neovim \

steam lutris wine-staging \

htop ncdu bleachbit rakuai-cli

After installing Docker, add your user to the docker group:

sudo usermod -aG docker $USER

newgrp docker   # reload groups without reboot

Setting Zsh as default shell

chsh -s /usr/bin/zsh

Log out/in to see the new prompt.

8. Common Pitfalls & Troubleshooting

sudo fallocate -l 8G /swapfile

sudo chmod 600 /swapfile

sudo mkswap /swapfile

sudo swapon /swapfile

Add entry to /etc/fstab. | | sudo asking for password repeatedly | User not in wheel group. | sudo usermod -aG wheel $USER; log out/in. | | Unable to mount ZFS pool | Kernel module not loaded. | sudo modprobe zfs; enable zfs-import-cache.service. | | RakuAI CLI returns “model not found” | Offline mode or missing cache. | Run rakuai-cli –download-model while connected to the internet. |

For deeper logs, examine journalctl -b -p err or look at /var/log/installer.log (available after a failed install).

9. Tips for a Smooth Experience on Dual‑Boot or UEFI Systems

1. Turn off Fast Boot & Secure Boot (temporarily) – Some laptops lock the EFI variables, preventing the installer from writing to the ESP. You can re‑enable Secure Boot after installation; RakuOS provides signed Shim binaries.
2. Create an EFI backup – Before overwriting the ESP, copy its content:
3. sudo cp -r /boot/efi /boot/efi-backup
4. Use the “Install alongside” option only if you’re sure the existing OS is using GPT. Mixing MBR & GPT on the same disk can break boot.
5. If you are installing on a laptop with an eMMC, ensure you select the correct drive (/dev/mmcblkX).
6. Set the bootloader priority via the firmware UI: place the “RakuOS” entry above Windows Boot Manager.

10. Wrapping Up – Where to Go From Here?
