[Bug Report & Solution] Root Cause of Grayed-Out ADB Debugging on Debian 13 (Trixie): Broken Google Repository
Hello Chrome OS Engineering Team, After extensive troubleshooting regarding the "Enable ADB debugging" toggle remaining grayed out on managed devices, I have isolated the root cause. It is not an Admin Policy issue, nor a user error. The issue is a missing dependency in the Google Package Repository for Debian 13 (Trixie), which prevents the installation of cros-guest-tools. Without cros-guest-tools, the Chrome OS Host cannot verify the container's integrity or establish the necessary bridges, leading the OS to lock developer features (ADB) as a security fallback. Here is the technical breakdown and the required fix. 1. The Environment Host: Chrome OS (Version 131+) Guest: Debian 13 (Trixie) - Current Stable. Repository Config: /etc/apt/sources.list.d/cros.list deb https://storage.googleapis.com/cros-packages/142 trixie main 2. The Error When attempting to install or update the integration tools via sudo apt install cros-guest-tools, the package manager fails with a hard dependency error: The following packages have unmet dependencies: cros-guest-tools : Depends: cros-im which is a virtual package and is not provided by any available package Running sudo apt search cros-im confirms that this package does not exist in the trixie RELEASE of the repository. 3. The Diagnosis The cros-guest-tools meta-package depends on cros-im (Input Method integration). In Bookworm (Debian 12), this dependency is satisfied (likely by cros-im-default or similar). In Trixie (Debian 13), the cros-im package has not been published or linked in the repository index. 4. The Solution (Action Required from Google) The repository maintainers need to push the missing input method packages to the Trixie DIRECTORY immediately. Required Action: Please ensure cros-im-default (or the architecture-specific equivalent) is added to: https://storage.googleapis.com/cros-packages/142/dists/trixie/main/ Once this dependency is resolvable: cros-guest-tools will install correctly. The Host<->Guest handshake will complete. The "Enable ADB Debugging" toggle will unlock in the Chrome OS Settings. Please escalate this to the Cros Packaging team. Best regards, Christophe Roux
