[FIX] Linux Mint / Debian: Antigravity 2.0 Update Loop & Missing IDE/Manager

Google Antigravity

When upgrading to Antigravity 2.0 on Linux Mint via the native package manager (apt update), Google’s architecture mismatch pulls down an outdated version (1.23.2). Because version 2.0 completely decouples the IDE (Editor) from the Agent Manager (Dashboard) into two separate apps, the legacy system files conflict. Launching from the system menu forces a “Redirect Loop” where the old background agent runner hijacks the launch commands, falsely screaming that an update is available or refusing to open entirely.

The Fix: Manual Isolation and Menu Restoration

If your system menu is completely broken or launching the wrong version, follow these exact steps to migrate your data, purge the broken repository code, and link the new standalone apps side-by-side.

Step 1: Clean Out the Conflicting Legacy Package

  1. Open your terminal (Ctrl + Alt + T) and kill any frozen background processes:

    Bash

    pkill -f antigravity

  2. Completely purge the broken apt repository installation (this will not delete your local project source code folders):

    Bash

    sudo apt purge antigravity

  3. Remove stale desktop shortcuts and clear out the system-wide app cache:

    Bash

    sudo rm -f /usr/share/applications/antigravity.desktop
sudo update-desktop-database
rm -rf ~/.antigravity

Step 2: Download the Raw Standalone Binaries

Do not use the standard apt repository or the main download button. Go directly to antigravity.google/download:

  1. Download the Antigravity IDE archive (.tar.gz).

  2. Download the standalone Antigravity 2.0 Agent Manager Linux x64 package.

  3. Extract both archives into your ~/Downloads directory.

Step 3: Grant Executable Permissions

Linux Mint treats raw binary executables as text data until explicitly unblocked.

  1. Open your file manager and navigate to your extracted folders.

  2. In the Antigravity IDE folder, right-click antigravity-ide → Properties → Permissions → Check “Allow executing file as program”.

  3. In the Antigravity-x64 folder, right-click antigravity → Properties → Permissions → Check “Allow executing file as program”.

Step 4: Rebuild the Mint Main Menu Shortcuts Manually

Since these are portable binaries running out of your local folders, force Linux Mint to display them side-by-side in your taskbar menu:

  1. Right-click the green Linux Mint Menu button on your taskbar → click Configure.

  2. Go to the Menu tab → click Open the Menu Editor.

  3. Select the Programming (or Development) category on the left side.

Add the IDE Launcher:

  • Click New Item on the right.

  • Name: Antigravity IDE

  • Command: Click Browse → Navigate to ~/Downloads/Antigravity IDE/ → Select the antigravity-ide binary.

  • Click OK.

Add the Agent Manager 2.0 Launcher:

  • Click New Item on the right again.

  • Name: Antigravity Agent Manager 2.0

  • Command: Click Browse → Navigate to ~/Downloads/Antigravity-x64/ → Select the green antigravity binary.

  • Click OK.

The Result

Close the menu editor. Both apps will now sit cleanly side-by-side in your Mint application menu. Launching Antigravity IDE will load your workspace instantly without update prompt errors, and launching Agent Manager 2.0 will safely open your dedicated background orchestration panel!
