🦕 apt install deno

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

⚡ The short answer. On a stock system apt install deno fails outright — Deno is not in the official Debian or Ubuntu archives at all. Add the deb.griffo.io repository below and sudo apt install deno gives you the current release on Debian and Ubuntu alike — currently deno 2.9.5 (updated 2026-08-17).

📦 Add the repository, then apt install deno

Step 1: Add repository & key

Run the commands
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 $(lsb_release -sc) 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 $(lsb_release -sc) main" | tee /etc/apt/sources.list.d/deb.griffo.io.list > /dev/null
apt update

Step 2: apt install deno

sudo apt install -y deno
apt install -y deno

🔄 How to apt install the latest Deno

Once the repository is added there is no separate "install latest" command — apt already resolves to the newest version this repository serves, and that is rebuilt within hours of every upstream Deno release. To move an existing install up to the latest version:

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

Or upgrade everything on the machine at once with sudo apt update && sudo apt upgrade. To see which version you would get before installing, run apt policy deno.

❓ Common questions

Does apt-get install deno work too?

Yes. apt and apt-get read the same sources, so sudo apt-get install deno is equivalent. apt is the friendlier front-end; apt-get is the stable one to prefer inside scripts.

Why doesn't apt install deno work out of the box?

Deno is not packaged in the official Debian or Ubuntu archives, so a stock system has nothing to install and apt install deno fails with "Unable to locate package". Adding this repository gives apt a source that carries Deno and keeps it current.

Which Debian and Ubuntu releases are supported?

Every currently supported release listed in the table above. The $(lsb_release -sc) in the setup command picks the right suite for the machine you run it on, so the same three lines work everywhere.

Is this repository trustworthy?

It's 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, and the whole archive is GPG-signed. Several upstream projects link to it from their official installation docs.
