Codex Desktop for Linux

Unofficial Linux packaging for Codex Desktop.

User Installation (Release Only)

End users only need files from GitHub Releases. No need to clone this repo or install Node.js.

Release page: https://github.com/cuongducle/codex-linux/releases/latest

Ubuntu Support

• Supported target: Ubuntu 22.04 and newer
• Recommended: Ubuntu 24.04 or newer
• Unsupported: Ubuntu 20.04 and older

Option 1: Debian / Ubuntu (.deb)

1. Go to Releases.
2. Download the latest codex-desktop-*.deb file.
3. Install:

sudo apt install ./codex-desktop-*.deb

Option 2: Any Distro (.AppImage)

1. Go to Releases.
2. Download the latest codex-desktop-*-x86_64.AppImage.
3. Run:

chmod +x codex-desktop-*-x86_64.AppImage
./codex-desktop-*-x86_64.AppImage

Updating

• .deb: download and install the newer release file.
• .AppImage: replace the old AppImage with the new release file.

Maintainer Flow (Build + Publish)

1) Build locally

# Download upstream DMG
curl -fL "https://persistent.oaistatic.com/codex-app-prod/Codex.dmg" -o Codex.dmg

# Extract payload + rebuild Linux native modules
bash scripts/setup.sh ./Codex.dmg

# Build packages
npm run build:linux
# or separately:
# npm run build:deb
# npm run build:appimage

Output artifacts are in dist/.

2) Publish release

Push a version tag:

git tag v0.1.0
git push origin v0.1.0

GitHub Actions will automatically:

• Build .deb and .AppImage
• Upload both files to GitHub Releases
• Generate APT repository metadata (Packages, Release)
• Publish APT repo to gh-pages

Daily Auto-Update

Workflow check-upstream.yml runs daily and:

• Sends a HEAD request to upstream Codex.dmg and checks ETag first
• If ETag is unchanged: skip download
• If ETag changed: download Codex.dmg, extract Codex app version from app.asar/package.json
• Compares that version with latest git tag (v*)
• If newer: updates upstream-version.txt, updates upstream-etag.txt, commits, and creates a new tag v<codex-version>

That new tag triggers the release workflow, which publishes new .deb, .AppImage, and refreshed APT metadata.

Required Repository Settings

1. Enable GitHub Pages:

• Settings -> Pages -> Source: Deploy from a branch
• Branch: gh-pages (root)

2. Keep repository public (for public downloads).

3. Add repository secret RELEASE_PAT (recommended):

• Create a Personal Access Token with repo + workflow scopes.
• Save it in repo Settings -> Secrets and variables -> Actions -> RELEASE_PAT.
• This is used by daily update workflow to push tags that can trigger downstream release workflow.

Features

• Packaging targets: DEB and AppImage only
• Linux native module rebuild (better-sqlite3, node-pty)
• Release CI runs on current Ubuntu runners with dmg2img and 7zip
• Auto-upload release artifacts (.deb, .AppImage) to GitHub Releases
• Optional APT repo publish on release tag

Repository Structure

• scripts/setup.sh - Extract from DMG, rebuild native modules, local launcher setup
• scripts/build-packages.sh - Build DEB/AppImage via electron-builder
• scripts/build-apt-repo.sh - Generate Debian repository metadata
• scripts/generate-apt-install-script.sh - Generate public install.sh
• .github/workflows/release.yml - CI build + release + APT publish
• electron-builder.yml - Packaging config

Notes

• This is an unofficial packaging project.
• This repository does not redistribute Codex source; it builds from upstream Codex.dmg.
• APT setup currently uses trusted=yes (unsigned repository).
