Troubleshooting

Diagnose and resolve common anomalies with installation PATHs, local self-updating locks, keyring access permissions, and SSH clipboard forwarding.

Quick reference

Scan the lookup table below to identify symptoms and access immediate solutions:

Configure your shell PATH

Symptom

Executing agy returns a shell terminal error:

bash: agy: command not found

Cause

The installation utility downloads the binary to ~/.local/bin (or C:\Users\\<username\>\AppData\Local\agy\bin), but your shell’s active $PATH environment does not index this directory.

Resolution

Ensure your terminal session loads the binary path.

macOS & Linux:

1. Open your shell configuration file (~/.bashrc or ~/.zshrc).

2. Verify or append the following line at the end of the file:

   export PATH="~/.local/bin:$PATH"

3. Reload your profile configurations:

   source ~/.zshrc

Windows (PowerShell):

1. Open a PowerShell terminal as an Administrator and execute:

   [System.Environment]::SetEnvironmentVariable("Path", [System.Environment]::GetEnvironmentVariable("Path", "User") + ";C:\Program Files\Google\antigravity-cli", "User")

2. Restart your terminal emulator for the system registry environment to refresh.

Authorize keyring permissions

Symptom

When launching, the CLI hangs, prints DBUS warnings, or throws keyring access exceptions:

Error: failed to retrieve token: secret keyring is locked

Cause

Antigravity CLI utilizes secure keychain libraries (Apple Keychain, Linux secret-service via dbus, or Windows Credential Manager) to encrypt your session tokens. If the background daemon is locked or headless, the CLI cannot read credentials.

Resolution

macOS:

1. Open Keychain Access app.

2. Search for the Antigravity CLI security item.

3. Right-click, select Get Info, choose the Access Control tab, and verify that agy is on the allowed applications list.

4. If running inside a headless SSH session on Mac, run the following unlock sequence:

   security unlock-keychain -p "your_keychain_password" login.keychain

Linux:

Ensure your system keyring (such as GNOME Keyring or KWallet) is unlocked and accessible.

If you are running in a headless environment or over SSH, ensure that a D-Bus session is active and that your keyring daemon is running. You can typically initialize a D-Bus session by running:

export $(dbus-launch)

If you still experience access issues, ensure your user account has the necessary permissions to access the keyring service or reach out to support.

Enable emulator clipboard forwarding

Symptom

Pasting screenshots or media files via Ctrl+V within an SSH terminal returns a failure notification:

Error: local pasteboard is empty or unreachable over SSH connection

Cause

Standard SSH streams do not forward graphical clipboards. Graphic uploads require specific terminal multiplexer protocols.

Resolution

Verify that you are utilizing supported terminal emulators and configurations.

1. Use iTerm2 or Ghostty: These emulators support advanced clip channels.

2. Configure iTerm2 Forwarding:

   • Open iTerm2 Preferences (Cmd+,).
   • Go to the General tab, select Selection submenu.
   • Check Applications in terminal may access clipboard (enabling OSC 52 write channels).

3. Bypass Multiplexers: If running inside tmux, ensure your active configuration maps standard paste clips correctly:

   set -s set-clipboard on

Resolve self-updater locks and failures

Symptom

Launching agy hangs, fails to apply upgrades, or returns an advisory lock warning:

Warning: another background updater process is already active (update.lock)

Cause

Antigravity CLI contains a native, statically linked self-updater that runs in the background. It uses a 15-minute Time-To-Live (TTL) debounce marker (last_check.timestamp) and an advisory lock (update.lock) inside ~/.gemini/antigravity-cli/updater/ to prevent concurrent process collisions. If a background updater process hangs, crashes without releasing the lock, or has insufficient user filesystem permissions inside the executable directory, subsequent updates are blocked.

Resolution

• Release the advisory lock: Purge the background lock file manually:

  rm -f ~/.gemini/antigravity-cli/updater/update.lock

• Opt-out/Disable auto-updates: Set the AGY_CLI_DISABLE_AUTO_UPDATE environment variable to true inside your shell profile (~/.bashrc or ~/.zshrc):

  export AGY_CLI_DISABLE_AUTO_UPDATE=true

• Verify directory write permissions: Ensure your user profile owns and has write permissions inside the target installation directory (~/.local/bin/ on Unix, or %LOCALAPPDATA%\agy\bin on Windows).
