OS: Linux (Ubuntu Focal)
Issue: I am stuck in an onboarding loop. I cannot sign in.
Symptoms:
Browser shows “Authenticated Successfully,” but the editor remains logged out.
Clicking the “Open Link” button in the browser triggers an error in the editor: “The extension ‘google.login’ cannot be installed because it was not found.”
Logs (Antigravity Agent):
http: TLS handshake error from 127.0.0.1:XXXXX: remote error: tls: unknown certificate
Cache(userInfo): Singleflight refresh failed: You are not logged into Antigravity.
Attempted Fixes: Deep purge/reinstall, clearing ~/.config/Antigravity, setting Firefox/Chrome as default, and manual xdg-settings protocol handling. Nothing works.
