🐟 Install fish on Debian 12 “Bookworm”

The friendly interactive shell, with autosuggestions and syntax highlighting out of the box

← fish overview & all releases
📦 Currently serving: fish 4.8.1-1~bookworm for bookworm (updated 2026-08-17) — architectures: amd64, arm64. This page is regenerated automatically from the repository metadata, so the version above is exactly what apt install fish gives you today.

Debian 12 “Bookworm” is the previous Debian stable release (oldstable), still widely deployed on servers and desktops. fish is not shipped at its latest version by the official Debian archives, so this repository builds current upstream releases as native .deb packages targeted specifically at bookworm, with dependencies matching what Debian 12 actually ships.

And then it keeps doing it. Every new upstream release is packaged and published here within hours, so fish 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 fish on bookworm

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 bookworm 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 bookworm main" | tee /etc/apt/sources.list.d/deb.griffo.io.list > /dev/null
apt update

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

Step 2: Install fish

sudo apt install -y fish
apt install -y fish

🔄 Updating

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

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

🗑️ Uninstalling

sudo apt remove fish
# 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 fish
# 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 fish package?

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

Why not install fish from the official Debian archive?

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

How quickly do new fish 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 bookworm?

fish is currently built for: amd64, arm64.
