Native deployment — multi-distro guide

This guide covers running SelenaCore on Linux distributions beyond the primary-tested Debian/Ubuntu family (Raspberry Pi OS, Jetson L4T, Debian 12, Ubuntu 22.04/24.04). The installer now auto-detects the package manager and provides best-effort support for Fedora/RHEL, Arch, and openSUSE.

Tested on: Jetson L4T, Raspberry Pi OS, Debian 12, Ubuntu 22.04/24.04.

Community-supported (best-effort): Fedora 40+, RHEL 9 / Rocky / Alma, Arch Linux / Manjaro, openSUSE Tumbleweed / Leap 15.5+.

Report issues: https://github.com/dotradepro/SelenaCore/issues

Requirements (all distros)

• systemd (SelenaCore uses systemd units for smarthome-core, smarthome-agent, piper-tts, selena-display). Non-systemd init systems (OpenRC on Alpine, runit on Void) are not supported — the wizard will skip native-service installation and print instructions.
• 64-bit CPU (amd64 / arm64). armv7 Raspberry Pi 3 is not supported.
• 4 GB RAM minimum (8 GB recommended for local LLM).
• Docker Engine 24+ with the Compose plugin.
• Python 3.9+ on the host (the installer auto-installs a newer one via uv if the system interpreter is too old).
• NVIDIA GPU owners: NVIDIA drivers + Container Toolkit (installer handles this on apt/dnf/pacman/zypper).

One-command install

git clone https://github.com/dotradepro/SelenaCore.git
cd SelenaCore
sudo ./install.sh

The installer:

1. Detects the package manager (apt / dnf / pacman / zypper).
2. Installs base packages (curl, git, Python, ffmpeg, arp-scan, NetworkManager, build toolchain, …).
3. Installs Docker Engine + Compose plugin.
4. Installs native AI runtimes (Ollama + Piper TTS) on the host.
5. Sets up the selena system user and directory layout.
6. Starts the docker stack (core, agent) on port 80.
7. Prints http://<lan-ip>/ — open it in a browser to finish via the wizard.

The wizard then downloads STT/TTS/LLM models, creates the admin user, registers the device with the platform, and enables the systemd services.

Session user & kiosk binding

SelenaCore runs two classes of services:

Service	Runs as	Why
smarthome-core.service (Docker container)	selena system user	Background daemon — no seat, no home dir needed
selena-display.service (cage kiosk)	operator user	Wayland compositor needs a login seat, root has none
piper-tts.service (optional)	operator user	Stores voice models under ~/.local/share/piper/

"Operator user" = the human who sits in front of the device (or, for headless installs, any existing non-root user). By default install.sh uses $SUDO_USER — the user who ran sudo ./install.sh.

Picking the right user

# Case 1 — logged in as the operator, use sudo:
pi@raspberrypi:~ $ sudo ./install.sh
# → binds kiosk/piper to `pi`, adds `pi` to docker+selena groups

# Case 2 — SSH as root (no sudo), or any other case where $SUDO_USER is
# empty/root, you MUST pass --kiosk-user:
root@box:~ # ./install.sh --kiosk-user=alice
# → binds kiosk/piper to `alice`

# Case 3 — install.sh refuses to bind kiosk to root automatically.
# If no --kiosk-user is passed and $SUDO_USER is empty/root, the
# selena-display.service setup is SKIPPED with a warning. Everything
# else installs normally — you can enable the kiosk later by re-running
# install.sh with --kiosk-user=NAME.

Changing the operator later

Re-run sudo ./install.sh from the new user's session, or pass --kiosk-user=<newname>. The selena-display.service and piper-tts.service units get regenerated against the new user; the old user stays in docker and selena groups (harmless). No uninstall needed.

What about the selena system user?

Created automatically by install.sh — a system user (no shell, no login) that owns the docker container, /var/lib/selena, and /secure. You never log in as selena. Human operators get added to its group so they can read/write shared log and model directories.

Per-distro notes

Debian / Ubuntu / Raspberry Pi OS / Jetson L4T

No extra steps. This is the primary tested path.

Fedora / RHEL / Rocky / Alma (dnf)

sudo dnf install -y git curl
git clone https://github.com/dotradepro/SelenaCore.git
cd SelenaCore
sudo ./install.sh

Notes:

• Docker is installed via https://get.docker.com which configures the docker-ce repo and pulls the Compose plugin.
• NVIDIA Container Toolkit is installed from nvidia.github.io/libnvidia-container/stable/rpm/.
• SELinux: if enabled in enforcing mode, you may need to relabel /var/lib/selena and /secure:

  sudo chcon -R -t container_file_t /var/lib/selena /secure

• Firewall: firewalld is on by default. Open port 80:

  sudo firewall-cmd --permanent --add-service=http && sudo firewall-cmd --reload

Arch Linux / Manjaro (pacman)

sudo pacman -Syu --needed git curl
git clone https://github.com/dotradepro/SelenaCore.git
cd SelenaCore
sudo ./install.sh

Notes:

• Docker and NVIDIA Container Toolkit come from official Arch repos (community). If nvidia-container-toolkit is missing, install from AUR.
• cog and seatd are not installed automatically on Arch — only cage + wtype. Kiosk mode works; selena-display.service will use cage directly.

openSUSE Tumbleweed / Leap (zypper)

sudo zypper install -y git curl
git clone https://github.com/dotradepro/SelenaCore.git
cd SelenaCore
sudo ./install.sh

Notes:

• Docker installed via https://get.docker.com.
• NVIDIA toolkit repo added via zypper addrepo from the NVIDIA RPM mirror.
• AppArmor/SELinux are typically off; no extra steps.

Manual install (no install.sh)

If you prefer to do it by hand:

# 1. Install base packages (adapt to your distro)
#    See install.sh `install_host_packages` for the full list.

# 2. Install Docker + Compose
curl -fsSL https://get.docker.com | sh
sudo systemctl enable --now docker
sudo usermod -aG docker "$USER"

# 3. Install Ollama (host service, all distros)
curl -fsSL https://ollama.com/install.sh | sh
sudo systemctl enable --now ollama

# 4. Install Piper TTS Python package (as non-root user)
pip install --user piper-tts aiohttp

# 5. Create directories
sudo install -d -m 0755 /var/lib/selena/models/{piper,vosk,whisper} \
    /var/lib/selena/speaker_embeddings /var/log/selena
sudo install -d -m 0750 /secure

# 6. Clone and configure
git clone https://github.com/dotradepro/SelenaCore.git /opt/selena-core
cd /opt/selena-core
cp config/core.yaml.example config/core.yaml
cp .env.example .env

# 7. Build frontend + start stack
npx vite build
docker compose up -d --build

# 8. Stage systemd units (wizard will enable them)
sudo bash scripts/install-systemd.sh

# 9. Open http://<ip>/ and run the wizard

Troubleshooting

Installer exits with "PKG not found"

You're on a distro with none of apt/dnf/pacman/zypper. SelenaCore does not support nixpkgs, xbps (Void), apk (Alpine), or eopkg (Solus) out of the box. Use the Manual install section above, adapting package names by hand.

Ollama does not start

systemctl status ollama
journalctl -u ollama -n 50

Most common cause: GPU driver missing or port 11434 taken. Override with OLLAMA_HOST=127.0.0.1:11435 in /etc/systemd/system/ollama.service.d/override.conf and update llm.ollama_url in config/core.yaml.

Piper TTS service fails

scripts/piper-tts.service is templated with __USER__, __HOME__, __PYTHON__. If Piper fails, re-run:

sudo bash scripts/install-systemd.sh

which re-substitutes the placeholders based on current config.

Container cannot access PulseAudio

The docker-compose.yml mounts /run/user/${HOST_UID}/pulse. If your session is rootless / headless / lingering-disabled, the socket may be absent. Enable linger:

sudo loginctl enable-linger "$USER"

Then re-create the compose stack:

docker compose down && docker compose up -d

arp-scan returns empty list

arp-scan needs raw-socket capability. The compose runs the container with network_mode: host + privileged: true, which is required. On non-Debian distros, verify the container inherits these flags:

docker inspect selena-core | grep -E 'NetworkMode|Privileged'

SELinux blocks the container (Fedora/RHEL)

sudo setenforce 0   # verify
# If that fixes it, relabel the install paths:
sudo chcon -R -t container_file_t /var/lib/selena /secure /opt/selena-core
sudo setenforce 1

Contributing non-Debian testing feedback

If you run SelenaCore on a distro outside the tested set, we'd love a report. Open an issue with:

• Distro + version (cat /etc/os-release)
• sudo ./install.sh --dry-run output
• First error or warning
• Output of docker compose logs core --tail 50

See CONTRIBUTING.md for details.
