🦕 Install Deno on Ubuntu 25.10 “Questing Quokka”

A secure runtime for JavaScript and TypeScript with built-in tooling

← Deno overview & all releases
📦 Currently serving: deno 2.9.2-1+questing for questing (updated 2026-07-14) — architectures: amd64, arm64. This page is regenerated automatically from the repository metadata, so the version above is exactly what apt install deno gives you today.

Ubuntu 25.10 “Questing Quokka” is the current interim Ubuntu release. Deno is not shipped at its latest version by the official Ubuntu archives, so this repository builds current upstream releases as native .deb packages targeted specifically at questing, with dependencies matching what Ubuntu 25.10 actually ships.

🚀 Install Deno on questing

Step 1: Add the deb.griffo.io repository

sudo install -d -m 0755 /etc/apt/keyrings curl -fsSL https://deb.griffo.io/EA0F721D231FDD3A0A17B9AC7808B4DD62C41256.asc | sudo gpg --dearmor --yes -o /etc/apt/keyrings/deb.griffo.io.gpg echo "deb [signed-by=/etc/apt/keyrings/deb.griffo.io.gpg] https://deb.griffo.io/apt questing main" | sudo tee /etc/apt/sources.list.d/deb.griffo.io.list > /dev/null sudo apt update
install -d -m 0755 /etc/apt/keyrings curl -fsSL https://deb.griffo.io/EA0F721D231FDD3A0A17B9AC7808B4DD62C41256.asc | gpg --dearmor --yes -o /etc/apt/keyrings/deb.griffo.io.gpg echo "deb [signed-by=/etc/apt/keyrings/deb.griffo.io.gpg] https://deb.griffo.io/apt questing main" | tee /etc/apt/sources.list.d/deb.griffo.io.list > /dev/null apt update

The sources line above pins the questing suite explicitly, so it keeps working in containers and images where lsb_release is unavailable.

Step 2: Install Deno

sudo apt install -y deno
apt install -y deno

🔄 Updating

Updates arrive through normal system maintenance — new upstream releases are usually packaged within hours:

sudo apt update && sudo apt install --only-upgrade deno

🗑️ Uninstalling

sudo apt remove deno # optionally remove the repository as well: sudo rm /etc/apt/sources.list.d/deb.griffo.io.list /etc/apt/keyrings/deb.griffo.io.gpg

❓ Frequently asked questions

Is this an official Deno package?

No — deb.griffo.io is an unofficial repository maintained by Dario Griffo. Packages are built automatically from official upstream Deno releases; the packaging is open source at dariogriffo/deno-debian.

Why not install Deno from the official Ubuntu archive?

Ubuntu's archive freezes package versions when a release ships and afterwards receives mostly security and stability fixes, so fast-moving tools are either absent or several releases behind. This repository tracks upstream releases instead, with builds targeted at each Ubuntu release.

How quickly do new Deno releases arrive?

The repository polls upstream releases and publishes new builds automatically, typically within hours of an upstream release. Subscribe to the release feed to follow updates.

Which architectures are supported on questing?

deno is currently built for: amd64, arm64.
