Is Ruff in the official Ubuntu repositories?

No — Ruff is not packaged in the official Ubuntu archives. This free mirror serves the newest Ruff release that is at least 2 months old; the main repository at deb.griffo.io serves every release within hours of upstream.

How do I install the latest Ruff on Ubuntu?

Add the deb-free.griffo.io repository once using the instructions above, then run: sudo apt install ruff. New releases arrive through the normal sudo apt upgrade.

Are the packages signed and how are they built?

Every package is signed with the repository's GPG key (EA0F721D231FDD3A0A17B9AC7808B4DD62C41256) and built from upstream releases in public GitHub packaging repositories that anyone can inspect.

Which Ubuntu releases are supported?

Ubuntu 22.04 Jammy, 24.04 Noble, 25.10 Questing and 26.04 Resolute.

What is Ruff?

Ruff is an extremely fast Python linter and code formatter, written in Rust by Astral — the team behind uv. With over 800 built-in rules and native re-implementations of popular plugins, a single ruff binary replaces Flake8, isort, Black, pyupgrade, autoflake and dozens of plugins, while running 10–100× faster. It has become the default linter of the modern Python ecosystem, adopted by projects like FastAPI, Pandas and Hugging Face.

😤 Python tooling pain points: Managing flake8 plus a dozen plugins, isort fighting Black, minutes-long lint runs in CI, and installing linters into every single virtualenv? Ruff is one dependency-free binary that does it all in milliseconds — and installing it with apt makes it available system-wide, for every project and venv, without pip.

            🆓 Free forever, patched immediately: Debian and Ubuntu freeze package versions when a release ships; this free mirror instead serves the newest release once it is at least 2 months old, with security fixes published immediately. Want every release within hours instead? That's the main repository at deb.griffo.io.
        

⚡ Key Features of Ruff

🏎️ 10–100× Faster

Lints large codebases in milliseconds where legacy tools take minutes — fast enough to run on every save and in every CI pipeline.

🧰 One Tool, 800+ Rules

Re-implements Flake8, isort, pyupgrade, pydocstyle, eradicate and more — one config in pyproject.toml replaces a stack of plugins.

🖤 Drop-in Formatter

ruff format is a Black-compatible formatter — same style, orders of magnitude faster, no separate tool to install.

🔧 Auto-fixes

Hundreds of rules come with automatic fixes: unused imports, upgraded syntax, sorted imports — ruff check --fix and done.

🐍 Version-aware

Targets any Python from 3.7 onward with per-version rule behavior, monorepo-friendly hierarchical configuration and per-file overrides.

🔌 Editor Integrations

A built-in language server (ruff server) powers first-class VS Code, Zed, Neovim and Helix integrations from the same binary.

🏆 Why install it with apt?

System-wide, pip-free: one binary for every project, venv, CI job and user — no per-project installs to keep in sync
Perfect for Docker/CI images: bake the repo into base images and every pipeline gets current ruff automatically
No toolchain: no Rust, no cargo, no pip — a signed apt repository with prebuilt binaries for 8 architectures
Automatic updates: ruff releases frequently; apt upgrade keeps up so your rules never go stale
Pairs with uv: Astral's package manager is also served here — the full modern Python toolchain from one repository
