ChatGPT

The ChatGPT extension adds the ChatGPT desktop app, with Codex, to a Frostyard desktop image. Use it when you want the app on a desktop image. Every image carries the extension’s definition, switched off. The extension itself is not in the image: Updex turns it on and downloads it.

Before you start

Section titled “Before you start”

You need:

  • A Frostyard desktop bootc image: Snow, Snowfield, or Sundog, not Floe.
  • Root access to enable, update, and remove the extension.
  • Network access to https://repository.frostyard.org/ext/chatgpt/.
  • Free space in /var for the download and the installed image.

The ChatGPT extension has no published test results on Frostyard images yet. Try it on a machine you can spare first.

Enable ChatGPT

Section titled “Enable ChatGPT”

See what Updex found, then enable the feature and download it now:

Terminal window
updex features list --component=chatgpt
sudo updex features enable chatgpt --now

chatgpt appears as a component, with its feature disabled. The enable command downloads the image, checks its checksum and signature, links it, and refreshes the merge.

Check the merge and the files that the extension adds:

Terminal window
systemd-sysext status
command -v chatgpt
ls /usr/share/applications/chatgpt.desktop

systemd-sysext status lists chatgpt. command -v prints a path, and ls prints the launcher file.

If enable --now exits with a refresh error (refresh_error in JSON), the download worked, but the activation did not. If the output says activation did not finish, the extension is merged, but users and groups can be missing: reboot. Otherwise the merge state is unknown: reboot. A sudo systemd-sysext refresh by hand does not create users and groups. Then run the checks above again.

Use ChatGPT

Section titled “Use ChatGPT”

Start ChatGPT from your applications, or run chatgpt. The command runs the app’s codex-launcher. The extension ships no service and adds nothing to /etc.

Update, roll back, and remove

Section titled “Update, roll back, and remove”

See whether a newer image exists, then update:

Terminal window
updex features check --component=chatgpt
sudo updex features update --component=chatgpt

The update downloads the newest image and links it. A refresh replaces /usr under a running app, and a running app can fail. Close ChatGPT before you run updex features update, or update with --no-refresh and reboot. See Manage system extensions for the check output and the update timer.

Roll back with sudo updex features rollback chatgpt. It takes effect at the next boot. See Roll back.

Remove ChatGPT now:

Terminal window
sudo updex features disable chatgpt --now --force

Updex unmerges all extensions on the host, deletes the ChatGPT image, and merges the rest again. Your ChatGPT data stays in your home directory. Reboot when the command finishes. Without --force, Updex refuses while the image is merged.

What ships

Section titled “What ships”
Item What you get
Package requests chatgpt (from the OpenAI APT repository that the build uses) and libglib2.0-bin
Version The image file name carries the chatgpt version, plus a +rN snosi revision when one is set
Command and launcher /usr/bin/chatgpt, which points to /usr/lib/chatgpt/codex-launcher, and /usr/share/applications/chatgpt.desktop
Sandbox No SUID chrome-sandbox. The app uses unprivileged user namespaces
Services None
Image file chatgpt_<version>_<os>_<arch>.raw.zst; .raw.xz, .raw.gz, and .raw also work
Download From https://repository.frostyard.org/ext/chatgpt/, signature required (Verify=true), into /var/lib/extensions.d/

Each build checks that these paths are present: the ChatGPT binary, codex-launcher, the /usr/bin/chatgpt link, the launcher, and the icon in /usr/share/pixmaps. A build that is missing one fails.
