🐟 Install fish on Ubuntu 26.04 LTS “Resolute”

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

← fish overview & all releases
📦 Currently serving: fish 4.8.1-1~resolute for resolute (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.

Ubuntu 26.04 LTS “Resolute” is the newest long-term support Ubuntu release. fish 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 resolute, with dependencies matching what Ubuntu 26.04 LTS 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 resolute

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

The sources line above pins the resolute 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

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

❓ 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 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 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 resolute?

fish is currently built for: amd64, arm64.
