Install GitHub Copilot CLI 1.0.83, then connect again.

I get this error when trying to connect to my GitHub Copilot account: Install GitHub Copilot CLI 1.0.83, then connect again.

That message means FCC can't find a copilot executable on the PATH of the process running it. (If it finds one that isn't exactly 1.0.83, you get a slightly different message.)

FCC pins the Copilot SDK, so it only accepts Copilot CLI 1.0.83. It looks up copilot on PATH and, if it's missing, raises that error:

free-claude-code/src/free_claude_code/providers/github_copilot/native_cli.py

Lines 41 to 46 in 105bfab

	async def verified_cli_path(env: Mapping[str, str]) -> str:
	path = shutil.which("copilot", path=env.get("PATH"))
	if path is None:
	raise CopilotUnavailable(
	f"Install GitHub Copilot CLI {COPILOT_CLI_VERSION}, then connect again."
	)

It then runs copilot --version and requires the output to start with GitHub Copilot CLI 1.0.83. Any other version (newer included) is rejected:

free-claude-code/src/free_claude_code/providers/github_copilot/native_cli.py

Lines 65 to 75 in 105bfab

	if (
	process.returncode != 0
	or re.match(
	rf"GitHub Copilot CLI {re.escape(COPILOT_CLI_VERSION)}\.?(?:\r?\n|\Z)",
	stdout.decode("utf-8", errors="replace"),
	)
	is None
	):
	raise CopilotUnavailable(
	f"FCC requires GitHub Copilot CLI {COPILOT_CLI_VERSION} for its pinned SDK. Install that version and reconnect."
	)

Fix:

npm install -g @github/copilot@1.0.83
copilot --version

The second command should print GitHub Copilot CLI 1.0.83. Alternatively use the release build: https://github.com/github/copilot-cli/releases/tag/v1.0.83

Then fully restart FCC (and whatever terminal or launcher started it) so it picks up the new PATH, and click Connect again under Providers > OAuth providers > GitHub Copilot. This is also listed in the README:

free-claude-code/README.md

Lines 276 to 281 in 105bfab

	- GitHub Copilot uses your signed-in GitHub account and subscription. Install
	[Copilot CLI 1.0.83](https://github.com/github/copilot-cli/releases/tag/v1.0.83)
	on PATH, then choose **Providers → OAuth providers → GitHub Copilot → Connect**.
	Finish signing in, then select a `github_copilot/<model-id>` from the model picker.
	Available models and quotas depend on your subscription and organization policies.
	Restart an already-running agent after connecting.

If copilot --version works in your terminal but FCC still shows the error, FCC was started from a shell or service that doesn't have that npm global bin folder on PATH. Start it from the same terminal where copilot works.

This error occurs because the tool looks for the copilot executable in your system's environment PATH, and it specifically requires version 1.0.83.
To fix this:

1. Make sure GitHub Copilot CLI is installed globally on your system.
2. Ensure that you have version 1.0.83 installed (as different versions can trigger this check).
3. Verify that the copilot binary path is correctly added to your system's environment variables (PATH) so the process running it can locate it.
