🚀 One-Line Install

Linux/Mac:

curl -sL https://raw.githubusercontent.com/lizTheDeveloper/solarpunk_utopia/main/setup.sh | bash

Termux (Android):

pkg install curl -y && curl -sL https://raw.githubusercontent.com/lizTheDeveloper/solarpunk_utopia/main/setup.sh | bash

Or using wget:

wget -qO- https://raw.githubusercontent.com/lizTheDeveloper/solarpunk_utopia/main/setup.sh | bash

This installs everything and starts all services. Access at http://localhost:3000 when complete.

Running on Android (Termux)

Prerequisites

• Android 7.0+ (Android 11+ requires extra steps below)
• 2GB+ free storage
• Stable WiFi connection

Installation Steps

1. Install Termux from F-Droid (NOT Google Play - that version is broken)

   • Install F-Droid app: https://f-droid.org/
   • Search for "Termux" in F-Droid
   • Install Termux (version 0.118.x recommended)

2. Grant Permissions (IMPORTANT for Android 11+)

   • Open Android Settings → Apps → Termux → Permissions
   • Enable "Files and media" or "Storage"
   • For Android 11+: Enable "All files access" under Special app access

3. First Launch

   • Open Termux
   • Wait for bootstrap installation (2-5 minutes)
   • Do not touch anything until you see a $ prompt
   • If you get "Permission denied" errors, see troubleshooting below

4. Run the installer:

   pkg install curl -y && curl -sL https://raw.githubusercontent.com/lizTheDeveloper/solarpunk_utopia/main/setup.sh | bash

   Installation takes 5-15 minutes depending on your device.

5. Access the app in your phone's browser:

   # Open Chrome/Firefox and go to:
   http://localhost:3000

6. Keep services running after closing Termux:

   Prevent CPU sleep (required):

   termux-wake-lock

   This keeps services running even when screen is off.

   Start services in background:

   nohup ./run_all_services.sh > /dev/null 2>&1 &

   Prevent Android from killing Termux:

   • Settings → Apps → Termux → Battery → Unrestricted (or "Don't optimize")
   • This prevents Android from killing Termux in the background

   Keep screen on while working (optional, drains battery):

   • Settings → Display → Screen timeout → 30 minutes (or higher)
   • Or use Developer Options → Stay awake (while charging)

7. Auto-start on phone boot (optional):

   • Install Termux:Boot from F-Droid
   • Create startup script:

     mkdir -p ~/.termux/boot
     cat > ~/.termux/boot/start-solarpunk.sh << 'EOF'
     #!/data/data/com.termux/files/usr/bin/sh
     termux-wake-lock
     cd ~/solarpunk_utopia
     ./run_all_services.sh > /dev/null 2>&1 &
     EOF
     chmod +x ~/.termux/boot/start-solarpunk.sh

8. Check service health:

   curl http://localhost:8000/health

Troubleshooting Android Installation

"Unable to install bootstrap" or "Permission denied":

1. Clean reinstall (this fixes 90% of issues):

   # In Android Settings:
   Settings → Apps → Termux → Storage → Clear Data
   Settings → Apps → Termux → Uninstall
   
   # Then reinstall from F-Droid and grant permissions immediately

2. Android 11+ Phantom Process Issue:

   • If bootstrap keeps failing, you may need to disable phantom process killer
   • Requires ADB: adb shell "settings put global settings_enable_monitor_phantom_procs false"
   • Then reboot phone and reinstall Termux

3. Change repository mirror:

   termux-change-repo
   # Select "All repositories" → Choose a different mirror

4. Alternative: Use UserLAnd

   • If Termux won't work, install UserLAnd from Play Store/F-Droid
   • Choose Ubuntu distribution
   • Run the Linux installer instead

Services won't start:

• Make sure you have enough storage (check with df -h)
• Try killing existing processes: ./stop_all_services.sh then restart

Can't access localhost:3000:

• Check if services are running: ps aux | grep python
• Check logs: tail -f logs/dtn_bundle_system.log
• Make sure you're using http:// not https://

Vision

From the original specification:

"We're building the infrastructure for regenerative gift economy communities. This isn't just software—it's a tool for communities to coordinate mutual aid, share resources, plan permaculture work, and learn together, all without depending on corporate platforms or internet infrastructure."

When this system works, communes can:

• ✅ Share surplus food before it spoils
• ✅ Lend tools and equipment easily
• ✅ Coordinate seasonal planting and harvests
• ✅ Teach and learn skills within the community
• ✅ Plan work parties and events
• ✅ Track resource flows for accountability
• ✅ Operate entirely offline and autonomously

This is infrastructure for a better world. Let's build it together. 🌱

---

Status

Current: ✅ Production ready (28 of 31 systems complete) Next: Hardware deployment (Raspberry Pi APs, Android bridge nodes) Future: Multi-commune federation via NATS

Built with ❤️ for regenerative gift economy communities

Let's coordinate mutual aid without corporate platforms. Let's build solidarity infrastructure. Let's create the world we want to see. 🌱
