GitHub Copilot

The GitHub Copilot extension adds the GitHub Copilot desktop app 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/github-copilot/.
  • Free space in /var for the download and the installed image.

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

Enable GitHub Copilot

Section titled “Enable GitHub Copilot”

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

Terminal window
updex features list --component=github-copilot
sudo updex features enable github-copilot --now

github-copilot 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 github git-credential-copilot
ls '/usr/share/applications/GitHub Copilot.desktop'

systemd-sysext status lists github-copilot. Each name 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 GitHub Copilot

Section titled “Use GitHub Copilot”

Start GitHub Copilot from your applications, or run github. The launcher runs github %u. The extension also ships the git-credential-copilot command.

The extension ships no service and adds nothing to /etc. The app keeps your settings, credentials, and worktrees in its normal per-user locations.

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=github-copilot
sudo updex features update --component=github-copilot

The update downloads the newest image and links it. A refresh replaces /usr under a running app, and a running app can fail. Close GitHub Copilot 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 github-copilot. It takes effect at the next boot. See Roll back.

Remove GitHub Copilot now:

Terminal window
sudo updex features disable github-copilot --now --force

Updex unmerges all extensions on the host, deletes the GitHub Copilot image, and merges the rest again. Your settings, credentials, and repositories stay 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 The GitHub Copilot .deb (a pinned download), plus libayatana-appindicator3-1, libwebkit2gtk-4.1-0, and libgtk-3-0
Version The image file name carries the github package version, plus a +rN snosi revision when one is set
Commands and launcher /usr/bin/github, /usr/bin/git-credential-copilot, and /usr/share/applications/GitHub Copilot.desktop; support files are in /usr/lib/GitHub Copilot
Services None
Image file github-copilot_<version>_<os>_<arch>.raw.zst; .raw.xz, .raw.gz, and .raw also work
Download From https://repository.frostyard.org/ext/github-copilot/, signature required (Verify=true), into /var/lib/extensions.d/

Each build checks that these paths are present: both commands, the /usr/lib/GitHub Copilot directory, the launcher, and the 128-pixel icon. A build that is missing one fails.
