Phase 8: Implement Debian package creation (2025-12-27)

- Create debian/ directory structure with all required files:
  - control: Package metadata and dependencies
  - compat: Debhelper compatibility level
  - changelog: Version history
  - rules: Build instructions
  - install: File installation mappings
  - postinst: Post-installation setup (user, venv, setcap)
  - prerm: Pre-removal script (stop service)

- Update config.py to support dual-mode operation:
  - Auto-detects system installation (/opt/sensorpajen)
  - Uses /etc/sensorpajen for config in system mode
  - Falls back to PROJECT_ROOT/config for development

- Update scripts/approve-sensors.sh for system paths:
  - Detects system vs development installation
  - Uses correct venv and config paths

- Create scripts/verify-deb.sh: Automated build and verification

- Create debian/README.md: Comprehensive packaging documentation

Package features:
- System-wide installation to /opt/sensorpajen/
- Configuration in /etc/sensorpajen/ (preserved on upgrade/remove)
- Dedicated sensorpajen system user
- Automatic venv creation with dependencies
- Bluetooth capabilities set automatically
- Service auto-enabled but waits for config before starting
- Dual-mode code supports both system and development installations

- ✅ debian/sensorpajen.service - System-wide systemd unit
3. Create INSTALL.md:
- APT package installation steps
- Manual installation steps
- Configuration examples
- First-time setup guide
- Raspberry Pi specific instructionsds}, ${misc:Depends},
python3-bluepy,
python3-paho-mqtt,
bluetooth,
bluez
Description: Bluetooth temperature sensor monitor
Monitors Xiaomi Mijia LYWSD03MMC Bluetooth temperature sensors
and publishes data to MQTT broker.
```
#### Code Updates:
- ✅ Updated src/sensorpajen/config.py to detect system installation
- Checks for /opt/sensorpajen existence
- Uses /etc/sensorpajen for config in system mode
- Falls back to PROJECT_ROOT/config for development
- ✅ Updated scripts/approve-sensors.sh for dual-mode operation
- Detects system vs development installation
- Uses correct venv and config paths
- ✅ Created scripts/verify-deb.sh - Automated build and verification
3. Create `debian/rules`:
```makefile
#!/usr/bin/make -f
%:
dh $@ --with python3 --buildsystem=pybuild
override_dh_auto_install:
pytOption 1: APT Package (Recommended for Raspberry Pi)
1. Download and install the .deb package:
```bash
sudo dpkg -i sensorpajen_1.0.0_all.deb
sudo apt-get install -f # Fix any dependencies
```
2. Configure:
```bash
mkdir -p ~/sensorpajen/config
cp /usr/share/doc/sensorpajen/examples/sensorpajen.env.example ~/sensorpajen/config/sensorpajen.env
cp /usr/share/doc/sensorpajen/examples/sensors.json.example ~/sensorpajen/config/sensors.json
# Edit both files
nano ~/sensorpajen/config/sensorpajen.env
nano ~/sensorpajen/config/sensors.json
chmod 600 ~/sensorpajen/config/sensorpajen.env
```
3. Enable and start service:
```bash
systemctl --user enable sensorpajen
systemctl --user start sensorpajen
```
### Option 2: Development Installation
1. Clone Repository
```bash
git clone <repo> ~/sensorpajen
cd ~/sensorpajen
```
2. Create Virtual Environment
```bash
python3 -m venv .venv
source .venv/bin/activate
pip install -e .
```
#### Package Details:
- Package name: sensorpajen
- Version: 2.0.0-dev
- Architecture: all
- System paths:
- Application: /opt/sensorpajen/
- Configuration: /etc/sensorpajen/
- Service file: /etc/systemd/system/sensorpajen.service
- Examples: /usr/share/doc/sensorpajen/examples/
- Runs as dedicated sensorpajen user (system account)
- Auto-enables service but waits for configuration before starting
### Relative Paths (For Portability)
- **Project root**: `~/sensorpajen/` (or wherever you clone/install)
- **Application config**: `~/sensorpajen/config/`
- **Environment file**: `~/sensorpajen/config/sensorpajen.env` (0600)
- **Sensor mapping**: `~/sensorpajen/config/sensors.json` (0644)
- **Service file**: `~/.config/systemd/user/sensorpajen.service`
#### Build and Test:
```bash
# Build package
./scripts/verify-deb.sh
### Advantages of Relative Paths
- Works on any system (development, production, multiple Raspberry Pis)
- Easy to backup/restore entire directory
- No hardcoded paths in code
- Simple to deploy via git pull or package installation
- User service runs without sudo
# Or manually:
dpkg-buildpackage -us -uc -b
lintian ../sensorpajen_*.deb
### APT Package Installation
When installed via .deb package:
- **Python package**: `/usr/lib/python3/dist-packages/sensorpajen/`
- **Service file**: `/lib/systemd/user/sensorpajen.service`
- **Config templates**: `/usr/share/doc/sensorpajen/examples/`
- **User config**: `~/sensorpajen/config/` (created by user)sensorpajen
```
5. Verify
```bash
systemctl --user status sensorpajen
journalctl --user -u sensorpajen -f
```uetooth access
if [ "$1" = "configure" ]; then
PYTHON_PATH=$(readlink -f /usr/bin/python3)
setcap 'cap_net_raw,cap_net_admin+eip' "$PYTHON_PATH" || true
fi
#DEBHELPER#
```
# Install on Raspberry Pi:
scp ../sensorpajen_*.deb pi@raspberrypi:~/
ssh pi@raspberrypi
sudo apt install ./sensorpajen_*.deb
7. Create `debian/README.Debian`:
- Installation instructions
- Configuration guide
- Service management
# Configure:
sudo nano /etc/sensorpajen/sensorpajen.env
sudo nano /etc/sensorpajen/sensors.json
8. Build the package:
```bash
dpkg-buildpackage -us -uc -b
```
9. Test installation on Raspberry Pi:
```bash
sudo dpkg -i ../sensorpajen_1.0.0_all.deb
sudo apt-get install -f # Fix dependencies if needed
```
10. Create installation documentation:
- Package installation instructions
- Configuration setup after installation
- Service enablement
# Start:
sudo systemctl start sensorpajen
sudo journalctl -u sensorpajen -f
```

# Tasks
## Task: Debian Package Creation
**Status**: DONE (2025-12-27)
**Priority**: Medium
**Estimated Effort**: 4-6 hours
**Actual Effort**: ~5 hours
### Implementation Summary
Successfully created a complete Debian package infrastructure for system-wide installation on Raspberry Pi and Debian-based systems. The package provides:
- **System-wide installation** to `/opt/sensorpajen/` with dedicated user
- **Configuration management** via `/etc/sensorpajen/` (preserved on upgrades)
- **Automatic setup** including Python venv, dependencies, and Bluetooth capabilities
- **Dual-mode operation** supporting both system and development installations
- **Build verification** with automated script
### Files Created
#### Debian Package Files (debian/)
- `control` - Package metadata, dependencies, maintainer info
- `compat` - Debhelper compatibility (v13)
- `changelog` - Version history and release notes
- `rules` - Build instructions (Makefile)
- `install` - File installation mappings
- `postinst` - Post-installation script (creates user, venv, sets capabilities)
- `prerm` - Pre-removal script (stops service)
- `postrm` - Post-removal script (cleanup, preserves config)
- `sensorpajen.service` - System-wide systemd unit file
#### Updated Code
- `src/sensorpajen/config.py` - Auto-detects system vs development installation
- `scripts/approve-sensors.sh` - Supports both installation modes
- `scripts/verify-deb.sh` - Automated build and verification script (NEW)
### Installation Paths
**System Installation (via .deb):**
- Application: `/opt/sensorpajen/`
- Python venv: `/opt/sensorpajen/venv/`
- Configuration: `/etc/sensorpajen/`
- Service: `/etc/systemd/system/sensorpajen.service`
- Examples: `/usr/share/doc/sensorpajen/examples/`
- User: `sensorpajen` (system account, no login)
**Development Installation:**
- Application: `<project-root>/`
- Python venv: `<project-root>/.venv/`
- Configuration: `<project-root>/config/`
- Service: `~/.config/systemd/user/sensorpajen.service`
### Key Features Implemented

✅ Bluetooth capabilities set automatically (setcap)
✅ Systemd service enabled but not started (waits for config)
✅ Configuration preserved on upgrade/remove/purge
✅ Example configs copied to /etc/sensorpajen on first install
✅ Dual-mode code (auto-detects system vs dev)
✅ Automated verification script
✅ Full lintian compliance
### Build and Install
```bash
# Verify and build
./scripts/verify-deb.sh
# Or manually
dpkg-buildpackage -us -uc -b
lintian ../sensorpajen_*.deb
# Install on Raspberry Pi
scp ../sensorpajen_*.deb pi@raspberrypi:~/
ssh pi@raspberrypi
sudo apt install ./sensorpajen_*.deb
# Configure
sudo nano /etc/sensorpajen/sensorpajen.env
sudo nano /etc/sensorpajen/sensors.json

✅ Logs appear in `journalctl -u sensorpajen`
✅ Dual-mode operation works correctly
### Overview
Create a Debian `.deb` package for system-wide installation of sensorpajen on Raspberry Pi OS and other Debian-based systems. This enables easy distribution and installation via `apt`/`dpkg` instead of manual git clone + pip install.
### Functional Requirements
1. **System-Wide Installation**
- Install application to `/opt/sensorpajen/`
- Create Python virtual environment in `/opt/sensorpajen/venv/`
- Install systemd service file to `/etc/systemd/system/`
- Place configuration in `/etc/sensorpajen/`
- Put example configs in `/usr/share/doc/sensorpajen/examples/`
2. **Dedicated Service User**
- Create `sensorpajen` system user if not exists
- Service runs as `sensorpajen:sensorpajen`
- User has no login shell, no home directory (system account)
3. **Automatic Service Configuration**
- Auto-enable systemd service on installation
- Configure Bluetooth capabilities (setcap) automatically
- Service starts after installation if config exists
4. **Configuration Management**
- Install example configs to `/usr/share/doc/sensorpajen/examples/`:
- `sensorpajen.env.example`
- `sensors.json.example`
- `discovered_sensors.json.example`
- Actual config expected in `/etc/sensorpajen/`:
- `sensorpajen.env`
- `sensors.json`
- Do NOT overwrite existing config on upgrade
- Preserve config on package removal
- Keep config even on purge (user explicitly chooses)
- Postinst should copy the examples into `/etc/sensorpajen/` only if they are missing, leaving any existing config untouched
- Upgrades should refresh `/usr/share/doc/sensorpajen/examples/` with new defaults but never alter live configs under `/etc/sensorpajen/`
5. **Dependency Management**
- Depend on system packages: `python3`, `python3-venv`, `python3-pip`, `bluetooth`, `bluez`
- Create venv and install Python deps from PyPI in postinst script
- Use `pyproject.toml` for Python dependency specification
6. **Package Metadata**
- Package name: `sensorpajen`
- Section: `misc`
- Priority: `optional`
- Architecture: `all`
- Maintainer: Fredrik (fredrik@wahlberg.se)
- Homepage: Repository URL
- Description: "Raspberry Pi Bluetooth temperature sensor monitor"
- Depends: System packages
- Recommends: `mosquitto-clients` (optional)
- **Version Source**: Extract version from `pyproject.toml` during build process.
7. **Files to Include**
- All Python source code from `src/sensorpajen/`
- Scripts from `scripts/` (approve-sensors.sh)
- Systemd service file (system service, not user service)
- Example configuration files
- Documentation: `README.md`, `INSTALL.md`
- License file
### Acceptance Criteria

# Check package contents
dpkg-deb -c sensorpajen_2.0.0_armhf.deb
# Check for issues
lintian sensorpajen_2.0.0_armhf.deb
> On every upgrade, rewrite `/usr/share/doc/sensorpajen/examples/` with the new package-provided examples so admins always have the latest defaults, but never overwrite existing files under `/etc/sensorpajen/`.
### Automated Verification
Provide a script (e.g., `scripts/verify-deb.sh`) that runs the build and linting steps in a clean environment. The script should:
```
#!/bin/bash
set -e
./ci/build-debian.sh # builds the deb into a temp directory
lintian sensorpajen_*.deb
echo "Package verification succeeded"
```
Acceptable tooling: `bash`, `lintian`, `dpkg-deb`. If lintian reports errors, the script should fail and print the diagnostics so you can triage the issue.
```
#### 10. Installation Test
```bash
# Install
sudo dpkg -i sensorpajen_2.0.0_armhf.deb
# Copy and edit config
sudo cp /usr/share/doc/sensorpajen/examples/sensorpajen.env.example /etc/sensorpajen/sensorpajen.env
sudo cp /usr/share/doc/sensorpajen/examples/sensors.json.example /etc/sensorpajen/sensors.json
sudo nano /etc/sensorpajen/sensorpajen.env
# Start service
sudo systemctl start sensorpajen
# Check status
sudo systemctl status sensorpajen
sudo journalctl -u sensorpajen -f
# Test upgrade
# (make changes, rebuild, reinstall - config should persist)
# Test removal
sudo dpkg -r sensorpajen # Config stays
sudo dpkg -P sensorpajen # Config still stays
```
### File Paths Reference
| Purpose | Path |
|---------|------|
| Application code | `/opt/sensorpajen/src/sensorpajen/` |
| Python venv | `/opt/sensorpajen/venv/` |
| Scripts | `/opt/sensorpajen/scripts/` |
| Systemd service | `/etc/systemd/system/sensorpajen.service` |
| Active config | `/etc/sensorpajen/sensorpajen.env`, `/etc/sensorpajen/sensors.json` |
| Discovery data | `/etc/sensorpajen/discovered_sensors.json` |
| Example configs | `/usr/share/doc/sensorpajen/examples/*.example` |
| Documentation | `/usr/share/doc/sensorpajen/` |
| Approve script | `/opt/sensorpajen/scripts/approve-sensors.sh` |
### Configuration Updates Needed
When implementing, update these to use `/etc/sensorpajen`:
**`src/sensorpajen/config.py`**:
```python
# Change PROJECT_ROOT logic for system installation
if Path('/opt/sensorpajen').exists():
# System installation
PROJECT_ROOT = Path('/opt/sensorpajen')
CONFIG_DIR = Path('/etc/sensorpajen')
else:
# Development installation
PROJECT_ROOT = Path(__file__).parent.parent.parent
CONFIG_DIR = PROJECT_ROOT / "config"
```
**`scripts/approve-sensors.sh`**:
```bash
# Update paths for system installation
if [ -d "/opt/sensorpajen" ]; then
cd /opt/sensorpajen
source /etc/sensorpajen/sensorpajen.env
source venv/bin/activate
else
# Development mode
cd "$(dirname "$0")/.."
source config/sensorpajen.env
source .venv/bin/activate
fi
```
### Notes
- Package is **system-wide**, not user-scoped
- Config in `/etc/sensorpajen/` is **never** auto-deleted
- Service runs as dedicated `sensorpajen` user for security
- Virtual environment created post-install to handle PyPI dependencies
- Bluetooth capabilities set automatically
- Service enabled but not started until config exists
- Follow Debian package naming: `sensorpajen_2.0.0_armhf.deb`
- Test on fresh Pi before considering complete

# Debian Package Build Guide
This directory contains the Debian packaging files for **sensorpajen**, a Bluetooth temperature sensor monitor for Raspberry Pi.
## Overview
The Debian package installs sensorpajen as a **system-wide service** with:
- Installation to `/opt/sensorpajen/`
- Configuration in `/etc/sensorpajen/`
- Dedicated `sensorpajen` system user
- Systemd service integration
- Automatic Python virtual environment setup
- Bluetooth capability configuration
## Prerequisites
### Required Packages
```bash
sudo apt install \
debhelper \
dpkg-dev \
python3 \
python3-venv \
python3-pip
```
### Optional (for verification)
```bash
sudo apt install lintian
```
## Quick Start
### Automated Build and Verification
```bash
# From project root
./scripts/verify-deb.sh
```
This script will:
1. Check for required tools
2. Build the package
3. Show package contents
4. Run lintian checks
5. Display installation instructions
### Manual Build
```bash
# From project root
dpkg-buildpackage -us -uc -b
```
The `.deb` file will be created in the parent directory:
```bash
ls -lh ../sensorpajen_*.deb
```
## Build Output
```
../sensorpajen_2.0.0-dev_all.deb # Installable package
../sensorpajen_2.0.0-dev_armhf.build # Build log
../sensorpajen_2.0.0-dev_armhf.buildinfo # Build metadata
../sensorpajen_2.0.0-dev_armhf.changes # Changes file
```
## Package Verification
### Check Package Contents
```bash
dpkg-deb -c ../sensorpajen_*.deb
```
### Check Package Metadata
```bash
dpkg-deb -I ../sensorpajen_*.deb
```
### Run Lintian
```bash
lintian ../sensorpajen_*.deb
```
**Note**: Warnings are acceptable. Focus on fixing errors.
## Installation
### On Raspberry Pi
```bash
# Copy package to Pi
scp ../sensorpajen_*.deb pi@raspberrypi:~/
# SSH to Pi and install
ssh pi@raspberrypi
sudo apt install ./sensorpajen_*.deb
```
### Local Testing (Not Recommended)
Installing on your development machine will modify `/opt` and `/etc`:
```bash
sudo apt install ../sensorpajen_*.deb
```
**Warning**: This will create system directories and a system user on your dev machine.
## Post-Installation Configuration
After installing the package:
```bash
# 1. Edit MQTT credentials
sudo nano /etc/sensorpajen/sensorpajen.env
# 2. Configure sensors
sudo nano /etc/sensorpajen/sensors.json
# 3. Start the service
sudo systemctl start sensorpajen
# 4. Check status
sudo systemctl status sensorpajen
# 5. View logs
sudo journalctl -u sensorpajen -f
```

## Maintainer Scripts
### postinst (Post-Installation)
Runs after package installation:
1. Creates `sensorpajen` system user (if doesn't exist)
2. Creates `/etc/sensorpajen/` directory
3. Copies example configs to `/etc/sensorpajen/` (if missing)
4. Creates Python virtual environment in `/opt/sensorpajen/venv/`
5. Installs Python dependencies via pip
6. Sets Bluetooth capabilities on Python executable
7. Installs systemd service file
8. Enables service (but doesn't start until configured)
### prerm (Pre-Removal)
Runs before package removal:
1. Stops the sensorpajen service
2. Disables the service (on remove, not upgrade)
### postrm (Post-Removal)
Runs after package removal:
1. Removes systemd service file
2. Reloads systemd daemon
3. **Preserves** configuration in `/etc/sensorpajen/`
4. **Preserves** `sensorpajen` user
**Note**: Configuration and user are intentionally preserved to prevent data loss.
## Upgrade Behavior
When upgrading to a new version:
```bash
sudo apt install ./sensorpajen_2.1.0_all.deb
```
- ✅ Service is stopped during upgrade
- ✅ Old files are replaced
- ✅ Configuration in `/etc/sensorpajen/` is **preserved**
- ✅ Python dependencies are updated
- ✅ Service is restarted after upgrade
- ✅ Example files in `/usr/share/doc/` are updated
## Removal Behavior
### Remove (Keep Config)
```bash
sudo apt remove sensorpajen
```
- Service stopped and disabled
- Application files removed from `/opt/sensorpajen/`
- Configuration **preserved** in `/etc/sensorpajen/`
- User **preserved**
### Purge (Still Keeps Config)
```bash
sudo apt purge sensorpajen
```
- Same as remove
- Configuration still **preserved** (by design, for safety)
- User still **preserved**
### Complete Removal
To completely remove everything:
```bash
sudo apt purge sensorpajen
sudo rm -rf /etc/sensorpajen
sudo userdel sensorpajen
```
## Troubleshooting
### Build Fails: "debhelper: command not found"
```bash
sudo apt install debhelper
```
### Build Fails: "dh_python3: command not found"
```bash
sudo apt install dh-python
```
### Lintian Warnings About Permissions
The postinst script runs as root and sets file permissions. This is expected and safe.
### Package Won't Install: Dependency Issues
```bash
# Fix missing dependencies
sudo apt install -f
```
### Service Won't Start After Install
Check if configuration has been edited:
```bash
sudo journalctl -u sensorpajen -n 50
```
Common issues:
- MQTT_HOST still has example value
- sensors.json is empty
- Bluetooth adapter not available
### Bluetooth Capability Not Set
```bash
# Manually set capability
sudo setcap cap_net_raw,cap_net_admin+eip $(readlink -f /opt/sensorpajen/venv/bin/python3)
# Verify
getcap $(readlink -f /opt/sensorpajen/venv/bin/python3)
```
## Development Workflow
### Making Changes
1. Edit source code in `src/sensorpajen/`
2. Update version in `pyproject.toml`
3. Update `debian/changelog` with new entry
4. Rebuild package: `./scripts/verify-deb.sh`
5. Test on Raspberry Pi
### Version Numbering
- Development: `2.0.0-dev`
- Release: `2.0.0`
- Patch: `2.0.1`
Update in both:
- `pyproject.toml` (line 6: `version = "..."`)
- `debian/changelog` (first line)
### Testing on Pi
```bash
# Build
./scripts/verify-deb.sh
# Copy to Pi
scp ../sensorpajen_*.deb pi@raspberrypi:~/
# Install on Pi
ssh pi@raspberrypi
sudo systemctl stop sensorpajen # If upgrading
sudo apt install ./sensorpajen_*.deb
sudo systemctl status sensorpajen
```
