How to Install Paperless-ngx on Ubuntu 24.04

Paperless-ngx on Ubuntu 24.04 (Docker Compose + Redis + PostgreSQL + Nginx + SSL)

Paperless-ngx is an open-source document management system (DMS) that helps you scan, organize, tag, and search digital documents efficiently. It automatically processes PDFs and images using OCR (Optical Character Recognition) to make all your content fully searchable. Paperless-ngx provides a modern web interface, supports multiple users, and integrates with scanners, email imports, and cloud storage systems — making it a complete paperless office solution.

Running Paperless-ngx on Ubuntu 24.04 LTS (Noble Numbat) ensures a modern, secure, and long-term supported base for your document management environment. With Docker Compose, Redis, PostgreSQL, Nginx, and SSL encryption, you can build a robust, scalable, and privacy-respecting DMS that works reliably for both individuals and teams.

Security & Best Practices

Deploy behind Nginx with HTTPS (Let’s Encrypt or custom certificate).
Store database and Redis credentials securely in .env or Docker secrets.
Restrict PostgreSQL and Redis access to internal Docker networks.
Use UFW to allow only ports 80 and 443.
Keep Docker and Paperless-ngx images updated regularly.
Automate SSL renewals with Certbot or Traefik ACME integration.
Configure daily backups for PostgreSQL and media volumes.
Set appropriate file permissions for uploads and scanned directories.
Enable strong authentication and role-based permissions for users.

Typical Use Cases

Personal document management – organize invoices, receipts, and forms.
Small businesses – digitize paper archives and invoices.
Law firms and accountants – maintain secure, searchable client files.
Educational institutions – manage student or research documentation.
Government and NGOs – archive and index internal records securely.
Remote teams – centralize document access while keeping data private.

Deploying Paperless-ngx on Ubuntu 24.04 with Docker Compose, PostgreSQL, Redis, and Nginx delivers a powerful, private, and fully searchable document management system — transforming how you store and access documents while ensuring security, efficiency, and long-term data control.

Create Your Server Instance on Shape.Host

Before installing Paperless-ngx, you need a fresh Ubuntu 24.04 server.
Here is the exact process to create one using Shape.Host Cloud VPS:

Visit https://shape.host and log in to your dashboard.

Click the “Create” button in the upper-right corner.

Select “Instance.”

Choose the server location closest to you or your users.

Under Operating System, select Ubuntu 24.04 (64-bit).

Choose a server plan — minimum recommended:

2 vCPUs

4 GB RAM

20 GB SSD/NVMe

Click Create Instance to deploy your server.

Copy the server’s public IP address from the “Resources” section.

Now you can connect to it via SSH.

Connect to Your Server

Linux/macOS

ssh root@your_server_ip

This logs you into the remote server.

Windows

Use PuTTY and connect as root.

Step 1: Update Your System

apt update

This command refreshes Ubuntu’s package index, ensuring you install the latest versions of packages.

Step 2: Install Required Tools

apt install curl git gnupg ca-certificates lsb-release

These packages allow your system to:

curl → download files
git → clone repositories
gnupg → verify package signatures
ca-certificates → trust HTTPS connections
lsb-release → detect Ubuntu version code name

Step 3: Add Docker’s Official Repository

Download Docker’s GPG key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc

Fix permissions

chmod a+r /etc/apt/keyrings/docker.asc

Create keyring folder (if missing)

install -m 0755 -d /etc/apt/keyrings

Download key again (from your history)

curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc

Fix permissions again

chmod a+r /etc/apt/keyrings/docker.asc

Add the Docker repo

echo   "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] \
  https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo $VERSION_CODENAME) stable"   > /etc/apt/sources.list.d/docker.list

This ensures that Ubuntu installs Docker from the official Docker source, not from Ubuntu’s outdated repository.

Step 4: Install Docker Engine + Docker Compose

apt update
apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

This installs:

Docker Engine
Docker CLI tools
containerd runtime
Buildx
Docker Compose v2

Step 5: Enable and Start Docker

systemctl enable docker
systemctl start docker

enable = starts Docker automatically on system boot.
start = initializes Docker right now.

Step 6: Verify Docker Compose

docker compose version

If you see a version number, Docker Compose v2 is installed correctly.

Step 7: Create the Paperless-ngx Directory

mkdir -p /opt/paperless
cd /opt/paperless

This creates a dedicated folder for the application and switches to it.

Step 8: Generate a Secret Key

openssl rand -base64 32

This generates a secure random SECRET_KEY for Paperless-ngx.
Copy and save it — you will paste it into the environment variables.

Step 9: Create the Docker Compose File

nano /opt/paperless/docker-compose.yml

Paste your exact configuration:

services:

  redis:
    image: redis:7
    container_name: paperless_redis
    restart: unless-stopped

  db:
    image: postgres:15
    container_name: paperless_db
    restart: unless-stopped
    environment:
      POSTGRES_DB: paperless
      POSTGRES_USER: paperless
      POSTGRES_PASSWORD: strongpassword
    volumes:
      - db-data:/var/lib/postgresql/data

  webserver:
    image: ghcr.io/paperless-ngx/paperless-ngx:latest
    container_name: paperless_web
    depends_on:
      - db
      - redis
    ports:
      - "8000:8000"
    restart: unless-stopped
    environment:
      PAPERLESS_REDIS: redis://redis:6379
      PAPERLESS_DBHOST: db
      PAPERLESS_DBNAME: paperless
      PAPERLESS_DBUSER: paperless
      PAPERLESS_DBPASS: strongpassword
      PAPERLESS_SECRET_KEY: "PASTE_YOUR_SECRET_KEY_HERE"
      PAPERLESS_URL: "https://your-domain.com"
      PAPERLESS_TIME_ZONE: "Europe/Bucharest"
    volumes:
      - data:/usr/src/paperless/data
      - media:/usr/src/paperless/media
      - consume:/usr/src/paperless/consume

volumes:
  db-data:
  data:
  media:
  consume:

What each service does:

redis → queue engine used by Paperless
db → PostgreSQL database
webserver → the actual Paperless-ngx app
volumes → persistent storage so nothing is lost

Save file:
CTRL+O → ENTER → CTRL+X

Step 10: Start Paperless-ngx

docker compose up -d

-d runs containers in the background.

Step 11: Verify Containers

docker ps

You should see:

paperless_web
paperless_db
paperless_redis

all running.

Step 12: Access the Web Interface

Open your browser and visit:

http://YOUR_SERVER_IP:8000
