How to Install ChatGPT on Ubuntu

ChatGPT on Ubuntu now has an official desktop app. OpenAI launched it on August 11, 2026, in public preview. It supports Ubuntu 24.04 LTS and Ubuntu 26.04 LTS through a single .deb package.

Before this, Ubuntu users had no official app. You ran ChatGPT in a browser or used community-built clients. That still works, but the native app is the new headline answer.

This guide walks you through every route. You get the full install steps for the desktop app, the zero-install web app, a terminal option, and safe advice on unofficial clients.

The Fastest Way to Get ChatGPT on Ubuntu

The fastest way to get ChatGPT on Ubuntu is OpenAI's official desktop app. Download the .deb file from OpenAI's official download page, install it, and sign in. It works on Ubuntu 24.04 LTS and 26.04 LTS.

The app is a public preview. It may contain bugs, and early reviews are mixed. Do not rely on it for mission-critical work yet.

If you would rather not install anything, open Ubuntu in any browser and go to chatgpt.com. That has always worked and needs zero setup.

What the Official ChatGPT App Includes

The official ChatGPT desktop app bundles more than a chat window. It packs several OpenAI tools into one native Ubuntu program.

This matters because you get coding help and a browser without leaving the app. Some features need a paid plan, and the app is proprietary.

• ChatGPT and ChatGPT Work for everyday chat
• The Codex coding agent, which can run in your local repositories
• A built-in web browser
• The ability to read local files without uploading them elsewhere
• Extensions that let it control other apps

Install ChatGPT on Ubuntu Step by Step

Installing ChatGPT on Ubuntu takes about five minutes. Follow these numbered steps to install the official .deb package on Ubuntu 24.04 or 26.04.

The .deb adds an OpenAI apt repository to your system. That means future updates arrive through normal apt upgrades, like any other package.

• 1. Open OpenAI's official ChatGPT download page at chatgpt.com/download in your browser.
• 2. Download the Linux .deb file. Pick x64 for Intel or AMD chips, or Arm64 for Arm machines.
• 3. Install it the easy way: double-click the downloaded .deb to open it in Ubuntu's Software app, then click Install.
• 4. Prefer the terminal? Run sudo apt install ./chatgpt-desktop_*.deb from the folder holding the file.
• 5. Or use dpkg directly: sudo dpkg -i chatgpt-desktop_*.deb, then run sudo apt --fix-broken install if it reports missing dependencies.
• 6. Launch ChatGPT from your app menu and sign in with your ChatGPT or OpenAI account.
• 7. Get updates later with sudo apt update && sudo apt upgrade, since the installer added the OpenAI repo.

Run ChatGPT on Ubuntu with No Install

You do not need any app to use ChatGPT on Ubuntu. Open chatgpt.com in Chrome, Chromium, Brave, or Edge, sign in, and start chatting.

You can also install it as a Progressive Web App (PWA). This gives a windowed, app-like feel without a full download.

To install the PWA, open the address-bar menu in Chrome or Chromium and choose Install app. Firefox does not support PWA install, so use a Chromium-based browser for this.

• Zero install and always up to date
• Works in any modern Ubuntu browser
• PWA gives a clean, standalone window
• Good fallback while the native app is still in preview

ChatGPT in the Ubuntu Terminal

Developers can use ChatGPT in the Ubuntu terminal through Codex CLI. Codex is OpenAI's first-party command-line coding agent, and it is the main terminal answer today.

Install it with npm if you have Node.js 18 or later: npm install -g @openai/codex. Always use the scoped @openai/codex name.

OpenAI also ships a standalone installer that removes the Node.js requirement: curl -fsSL https://chatgpt.com/codex/install.sh | sh. Then check it with codex --version and sign in.

• Verify the install: codex --version
• Authenticate by signing in with your ChatGPT or OpenAI account
• Common mistake: the unscoped codex package is an unrelated 2012 project, not this tool
• The classic "act as a Linux terminal" prompt only simulates a shell in chat; it does not run real commands

Unofficial ChatGPT Clients for Ubuntu

Community-built desktop clients for ChatGPT still exist on Ubuntu. These are Electron or Tauri wrappers around the web app, hosted on GitHub.

They are unofficial and not made by OpenAI. Quality varies, and some popular projects have been archived or abandoned.

Install the official app first. If you still want a community client, vet the project before trusting it.

• Check the star count and how recently it was committed
• Read the open issues for red flags
• Confirm it is still maintained, not archived
• Treat any wrapper as third-party software you are responsible for

Is ChatGPT on Ubuntu Free?

ChatGPT on Ubuntu is free to start, on both the app and the web. You can sign in with a free account and chat at no cost through any of the methods above.

The official desktop app itself costs nothing to download and install. Some features inside it, like higher usage limits and advanced tools, need a paid ChatGPT plan.

Pricing and free-tier limits change over time. Check the current plans on OpenAI's site before you commit a team to a paid tier.

• The web app and the .deb app are free to install and use at the basic level.
• A paid plan unlocks higher limits and some advanced features.
• Codex CLI is free to install, but heavier use may need a paid plan.
• Verify current pricing on OpenAI's site, since tiers change.

Which ChatGPT Option Should You Pick on Ubuntu

Pick the route that matches how you work. Most Ubuntu users want the official desktop app, but the web app and terminal each fit clear cases.

There is no wrong choice here. All three connect to the same ChatGPT account.

• Want a native app with Codex and a browser: install the official .deb
• Want zero setup or a preview-free experience: use the web app or PWA
• Write code in the shell all day: use Codex CLI in the terminal
• Run an older or unsupported distro: stick with the web app for now

Getting the Most from ChatGPT on Ubuntu

ChatGPT on Ubuntu is finally a first-class experience. The official .deb app, the web app, and Codex CLI cover every workflow from casual chat to shell-based coding.

Start with the official app on Ubuntu 24.04 or 26.04, and keep the web app as your reliable backup while the desktop preview matures.

Once ChatGPT is running, the bigger win is wiring it into real workflows. That is where a focused audit pays off.
