Jeena 025228b83c deps: Switch from uv to plain venv and pip-tools

uv installs to ~/.local/bin which is not in PATH for systemd services,
and keeping uv updated on Ubuntu requires manual steps outside of apt.
Switch to a plain Python venv with pip-tools for dependency locking.

- Replace uv venv/sync with python3 -m venv --system-site-packages
- Generate requirements.txt with pip-compile from pyproject.toml
- Update service ExecStart to use .venv/bin/python directly
- Remove uv.lock and [tool.uv] from pyproject.toml
- Update README to document venv+pip-tools workflow

Raw Blame History

matrix-paperless-ingest

Monitors a Matrix room for PDF and JPEG files and uploads them to Paperless-ngx. Designed for rooms bridged from WhatsApp via mautrix-whatsapp.

Processes the full room history on startup (skips files already in Paperless)
Listens for new files indefinitely
Retries failed uploads with exponential backoff
State is tracked in a local SQLite database

Requirements

Python 3.11+
libolm + python-olm — must be installed via the system package manager because python-olm's build system is incompatible with modern CMake

Arch Linux:

sudo pacman -S libolm python-olm

Ubuntu:

sudo apt install libolm3 python3-olm

Setup

1. Clone and install dependencies

git clone <repo>
cd matrix-paperless-ingest
python3 -m venv .venv --system-site-packages
.venv/bin/pip install -r requirements.txt

2. Create a Matrix bot account

Create a new Matrix account for the bot on your homeserver (e.g. via Element), then invite it to the room you want to monitor and accept the invite.

3. Generate a Matrix access token

curl -XPOST 'https://jeena.net/_matrix/client/v3/login' \
  -H 'Content-Type: application/json' \
  -d '{
    "type": "m.login.password",
    "user": "@yourbot:jeena.net",
    "password": "yourpassword"
  }'

Copy access_token and device_id from the response. You can then delete the password from your notes — it is not needed again.

4. Find your Matrix room ID

In Element: open the room → Settings → Advanced → Internal room ID. It looks like !abc123:jeena.net.

5. Find your Paperless inbox tag ID

In Paperless-ngx, go to Tags and note the ID of your inbox tag, or look it up via the API:

curl -H 'Authorization: Token YOUR_TOKEN' https://paperless.jeena.net/api/tags/

6. Configure

cp .env.example .env
$EDITOR .env

Fill in all values:

MATRIX_HOMESERVER=https://jeena.net
MATRIX_USER=@yourbot:jeena.net
MATRIX_ACCESS_TOKEN=syt_...
MATRIX_DEVICE_ID=ABCDEFGH
MATRIX_ROOM_ID=!abc123:jeena.net

PAPERLESS_URL=https://paperless.jeena.net
PAPERLESS_TOKEN=your_paperless_api_token
PAPERLESS_INBOX_TAG_ID=1

7. Test

.venv/bin/python ingest.py

Watch the logs. It will process all historical messages, then listen for new ones. Press Ctrl-C to stop.

Install as a systemd user service

# Enable lingering so the service starts at boot without requiring login
loginctl enable-linger

# Install the service
mkdir -p ~/.config/systemd/user
cp matrix-paperless-ingest.service ~/.config/systemd/user/
systemctl --user daemon-reload
systemctl --user enable --now matrix-paperless-ingest

# Check logs
journalctl --user -u matrix-paperless-ingest -f

Updating dependencies

If you need to add or update a dependency, edit pyproject.toml and regenerate the locked requirements.txt:

.venv/bin/pip install pip-tools
.venv/bin/pip-compile pyproject.toml
.venv/bin/pip install -r requirements.txt

Viewing retry queue

sqlite3 state.db "SELECT filename, status, retry_count, datetime(next_retry, 'unixepoch') FROM processed_events WHERE status = 'failed';"

Moving to a new server

Copy the project directory to ~/matrix-paperless-ingest (including .env and state.db)
Install libolm3 and python3-olm via the system package manager
Run python3 -m venv .venv --system-site-packages && .venv/bin/pip install -r requirements.txt
Install the systemd user service as above
