Install Fireball Wrangler Host on Ubuntu (ARM)

First: check your computer

Run this in Terminal. It should print aarch64.

1. 1

   Which kind of computer is this?

   aarch64 means this page is the right one. x86_64 means you need the Intel/AMD version.

   $ uname -m

   Copy

   Terminal–□×

   you@ubuntu:~$ uname -m
   x86_64     ← Intel or AMD
   aarch64    ← ARM

Install with apt (recommended)

Add Fireball's signed repository once. Ubuntu then installs Wrangler and keeps it up to date with Software Updater, just like Firefox or any Ubuntu app.

1. 1

   Add Fireball's signing key

   This lets Ubuntu check every Wrangler update really comes from Fireball Enterprise.

   $ sudo wget -qO /usr/share/keyrings/fireball-wrangler-archive-keyring.gpg https://fireballwrangler.com/downloads/apt/fireball-wrangler.gpg

   Copy
2. 2

   Add the repository

   One line that tells apt where Wrangler lives.

   $ printf 'Types: deb\nURIs: https://fireballwrangler.com/downloads/apt\nSuites: stable\nComponents: main\nSigned-By: /usr/share/keyrings/fireball-wrangler-archive-keyring.gpg\n' | sudo tee /etc/apt/sources.list.d/fireball-wrangler.sources

   Copy
3. 3

   Install Wrangler

   Ubuntu asks for your password. After this, Software Updater brings each new version.

   $ sudo apt update && sudo apt install fireball-wrangler-host

   Copy

   Terminal–□×

   you@ubuntu:~$ sudo apt update && sudo apt install fireball-wrangler-host

   Install

3. 3

   Or install it from Terminal

   Same result, from the Downloads folder.

   $ cd ~/Downloads && sudo apt install ./fireball-wrangler-host_arm64.deb

   Copy

Or: run the AppImage

For other Linux versions, or to try Wrangler without installing it. It updates itself.

1. 1

   Download and run

   Download FireballWranglerHost-linux-arm64.AppImage, make it runnable, and open it.

   $ cd ~/Downloads && wget -q https://fireballwrangler.com/downloads/linux/FireballWranglerHost-linux-arm64.AppImage && chmod +x FireballWranglerHost-linux-arm64.AppImage && ./FireballWranglerHost-linux-arm64.AppImage

   Copy

Tools to install yourself

Wrangler sets up the AI tools for you. These few need your computer's own installer, so paste them into Terminal. Get ready shows the same commands if one is missing.

• Git

  Required. Your agents use it to work on code.

  $ sudo apt install git openssl

  Copy

• GitHub CLI

  Optional. Needed for GitHub Projects sync and for agents to open issues and pull requests.

  $ sudo apt install gh

  Copy

  Then sign in to GitHub:

  $ gh auth login

  Copy

• Keyring tools

  Usually already there. Wrangler keeps its sign-in in Ubuntu's keyring.

  $ sudo apt install libsecret-tools

  Copy

If something's off

App Center says “Something went wrong”.

Usually the wrong kind of .deb for this computer. Run uname -m: aarch64 needs fireball-wrangler-host_arm64.deb. Then install that one.

A sign-in link opened in Text Editor instead of the browser.

Fixed in Wrangler 0.1.23. Update, or open the account's card in Accounts, choose Copy Link, and paste it into Firefox.

How do I update?

With the apt repository: Software Updater (or sudo apt update && sudo apt upgrade). Installing any .deb from 0.1.24 on adds that repository for you, so this is usually all you need.

App Center says “Installed” for a newer .deb.

That's an Ubuntu App Center bug: it won't upgrade a package from a downloaded file. Install it from Terminal instead: sudo apt install ./fireball-wrangler-host_arm64.deb (from the folder it's in). After that, updates come through Software Updater.

How do I remove it?

sudo apt remove fireball-wrangler-host. Your agents' folders stay in your home folder until you delete them.
