🥟 Install Bun on Ubuntu 25.10 “Questing Quokka”

An all-in-one JavaScript runtime, bundler, test runner, and package manager

← Bun overview & all releases
📦 Currently serving: bun 1.3.14-5~questing for questing (updated 2026-08-18) — architectures: amd64. This page is regenerated automatically from the repository metadata, so the version above is exactly what apt install bun gives you today.

Ubuntu 25.10 “Questing Quokka” is the current interim Ubuntu release. Bun 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.

And then it keeps doing it. Every new upstream release is packaged and published here within hours, so Bun updates arrive the same way your system updates do — through apt upgrade, unattended-upgrades, or whatever already runs on your machine. No release page to watch, no version to compare, no dpkg -i to remember.

🚀 Install Bun on questing

Step 1: Add the deb.griffo.io repository

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 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

🆓 There is an always-free mirror. deb-free.griffo.io serves packages free forever — no account, no subscription, at most 2 months behind upstream, security fixes immediately. It currently carries Ghostty, Oh My Posh and Zed; Bun is not one of them, so the repository above is the only way to get it today — ask and it can be enrolled.

How the free mirror works →

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 Bun

sudo apt install -y bun
apt install -y bun

🔄 Updating

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

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

🗑️ Uninstalling

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

❓ Frequently asked questions

Is this an official Bun package?

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

Why not install Bun 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 Bun 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?

bun is currently built for: amd64.
