How to Install uv on Debian: The Fast Python Package Manager

uv is an extremely fast Python package and project manager written in Rust by Astral, the creators of Ruff. It’s designed to be a single tool that replaces pip, pip-tools, pipx, poetry, pyenv, twine, virtualenv, and more, while being 10-100x faster than traditional Python package managers.

While uv is gaining rapid adoption in the Python community for its incredible performance and comprehensive feature set, installing it on Debian systems requires some extra steps since it’s not available in the official Debian repositories yet.

Fortunately, there’s an easy solution: the unofficial debian.griffo.io repository provides pre-built Debian packages for uv and many other useful development tools.

What Makes uv Special?

Before diving into the installation, let’s understand why uv is revolutionizing Python package management:

🚀 Single tool replacement - Replaces multiple Python tools with one unified interface
⚡️ Incredible speed - 10-100x faster than pip thanks to Rust implementation
🗂️ Comprehensive project management - Universal lockfiles, workspaces, and dependency resolution
❇️ Script execution - Run Python scripts with inline dependency metadata
🐍 Python version management - Install and manage multiple Python versions
🛠️ Tool management - Install and run Python-based CLI tools like pipx
🔩 pip-compatible interface - Drop-in replacement for existing workflows
💾 Disk-space efficient - Global cache for dependency deduplication

Why Use debian.griffo.io?

The debian.griffo.io repository offers several advantages over manual installation:

Easy installation and updates through APT package manager
Automatic dependency management handled by Debian packaging
Consistent with Debian packaging standards
Supports multiple Debian distributions (Bookworm, Trixie, Sid)
Regular updates following uv’s release cycle
No need to compile from source or manage Rust toolchain

Prerequisites

Before we begin, make sure you have:

A Debian-based system (Bookworm, Trixie, or Sid)
sudo privileges
curl installed (install with sudo apt install curl if needed)

Step 1: Add the Repository

First, we need to add the GPG key and repository to your system. Run the following commands in your terminal:

# Add the GPG key
curl -sS https://debian.griffo.io/EA0F721D231FDD3A0A17B9AC7808B4DD62C41256.asc | sudo gpg --dearmor --yes -o /etc/apt/trusted.gpg.d/debian.griffo.io.gpg

# Add the repository
echo "deb https://debian.griffo.io/apt $(lsb_release -sc 2>/dev/null) main" | sudo tee /etc/apt/sources.list.d/debian.griffo.io.list

Let’s break down what these commands do:

GPG Key Addition: Downloads and installs the repository’s GPG key, ensuring package authenticity
Repository Addition: Adds the repository URL to your APT sources list, automatically detecting your Debian distribution

Step 2: Update Package Lists

After adding the repository, update your package lists:

sudo apt update

Step 3: Install uv

Now you can install uv using APT:

sudo apt install uv

This command will download and install the latest version of uv along with any required dependencies.

Step 4: Verify Installation

After installation, verify that uv is working correctly:

uv --version

You should see output similar to:

uv 0.8.3

You can also check the help to see all available commands:

uv --help

Getting Started with uv

Now that uv is installed, let’s explore some of its key features:

Project Management

Create a new Python project:

# Initialize a new project
uv init my-project
cd my-project

# Add dependencies
uv add requests numpy

# Run your project
uv run python main.py

# Create a lockfile
uv lock

# Sync dependencies
uv sync

Script Execution

uv can run Python scripts with inline dependencies:

# Create a script with inline dependencies
echo 'import requests; print(requests.get("https://httpbin.org/json").json())' > script.py
uv add --script script.py requests

# Run the script in an isolated environment
uv run script.py

Tool Management

Install and run Python tools:

# Run a tool temporarily
uvx cowsay "Hello from uv!"

# Install a tool globally
uv tool install black
black --version

# List installed tools
uv tool list

Python Version Management

uv can install and manage Python versions:

# Install Python versions
uv python install 3.11 3.12

# List available Python versions
uv python list

# Use a specific Python version
uv python pin 3.12

pip Interface

uv provides a drop-in replacement for pip commands:

# Create a virtual environment
uv venv

# Install packages (pip-compatible)
uv pip install django flask

# Generate requirements
uv pip compile requirements.in

# Sync requirements
uv pip sync requirements.txt

Updating uv

One of the biggest advantages of using the repository is easy updates. To update uv (and all other packages):

sudo apt update && sudo apt upgrade

uv can also update itself if installed via other methods:

uv self update

Other Available Packages

The debian.griffo.io repository doesn’t just provide uv. It also includes many other useful development tools:

zig: Modern systems programming language (installation guide)
lazydocker: Terminal UI for Docker
lazygit: Terminal UI for Git
yazi: Terminal file manager written in Rust
fzf: Command-line fuzzy finder
ghostty: Fast terminal emulator
And many more!

You can explore all available packages by browsing the repository at debian.griffo.io. If you’re interested in other development tools, check out our guide on How to Install Zig on Debian, which uses the same repository and installation process.

Troubleshooting

Repository Key Issues

If you encounter GPG key issues, make sure you’re using the correct key:

# Remove old key if it exists
sudo rm -f /etc/apt/trusted.gpg.d/debian.griffo.io.gpg

# Add the current key
curl -sS https://debian.griffo.io/EA0F721D231FDD3A0A17B9AC7808B4DD62C41256.asc | sudo gpg --dearmor --yes -o /etc/apt/trusted.gpg.d/debian.griffo.io.gpg

Package Not Found

If APT can’t find the uv package:

Ensure you’ve run sudo apt update after adding the repository
Check that your Debian distribution is supported (Bookworm, Trixie, or Sid)
Verify the repository was added correctly: cat /etc/apt/sources.list.d/debian.griffo.io.list

Permission Issues

If you encounter permission issues when using uv:

# Check uv installation
which uv
ls -la $(which uv)

# Ensure your user has proper permissions
groups $USER

Uninstalling

If you need to remove uv:

# Remove uv package
sudo apt remove uv

# Remove the repository (optional)
sudo rm /etc/apt/sources.list.d/debian.griffo.io.list
sudo rm /etc/apt/trusted.gpg.d/debian.griffo.io.gpg
sudo apt update

Performance Comparison

To appreciate uv’s speed, here’s a visual comparison of uv against other popular Python package managers:

uv Performance Comparison

The chart shows uv’s dramatic performance advantage when installing popular packages compared to poetry, pdm, and pip-sync. This speed improvement becomes even more significant with larger dependency trees and complex projects, making uv an excellent choice for both development and CI/CD environments.

Conclusion

Installing uv on Debian doesn’t have to be complicated. The debian.griffo.io repository provides an easy, maintainable way to install and keep uv up-to-date on your Debian system. With uv installed, you get:

Dramatically faster Python package management
Unified tooling that replaces multiple Python tools
Modern project management with lockfiles and workspaces
Seamless Python version management
