Error: Cannot autolaunch D-Bus without X11 $DISPLAY when using VisualStudioCodeCredential on Linux Codespace

[joshspicer]

Hello! I am trying to use the VisualStudioCodeCredential helper to create a credential in VSCode (connected through a linux (debian) GitHub Codespace).

Repro

1. Connect to a Codespace through the VsCode Client.

2. Attempt to getToken via the VisualStudioCodeCredential.

	const keyvaultUrl = getEnv('KEYVAULT_URL');

        useIdentityPlugin(vsCodePlugin);
	const credential = new VisualStudioCodeCredential();

	console.log('TOKEN', (await credential.getToken('https://vault.azure.net/.default')
                                        .catch((e) =>
		                            console.log('ERROR!!!!', e)
	)));

3. getToken fails with Error: Cannot autolaunch D-Bus without X11 $DISPLAY.

Hello @joshspicer !

It seems to me that an important part of the premise of the issue you’re brining to us is whether @azure/identity-vscode should work in Codespaces or not. At the moment, @azure/identity-vscode does not work in Codespaces. The first action item for me is to make this clear on the README of @azure/identity-vscode.

Now, why are we seeing this error?

@azure/identity-vscode relies on keytar to work. This D-Bus issue seems to be a relatively common issue with keytar, see 292, 433, 224, 9262, 132.

In summary, Keytar relies on secret readers like gnome-keyring, which are not installed on Codespaces by default.

The best we can do is to improve the error message we provide. However, at the moment it is not clear to me what kind of guidance we should show, since the solution varies. One approach I’m seeing requires users to start the gnome-keyring-deamon. Give us some time to discuss and agree on what message we can provide.
