Overview

Ubuntu Chroot, developed by ravindu644, is a comprehensive desktop-grade Linux subsystem engineered for rooted Android hardware. While user-space emulation tools like Termux or PRoot offer basic command-line utilities, they run into performance limits due to ptrace system call interception overhead, lack direct hardware access, and cannot execute system-level daemons like systemd or Docker.

Ubuntu Chroot deploys a genuine Ubuntu 24.04 LTS root filesystem directly on the Linux kernel powering Android. Utilizing proper Linux namespaces, it provides full hardware acceleration, near-native execution performance, and a complete graphical desktop experience with full isolation from Android’s host userland.

Prerequisites & Compatibility

  • Hardware: ARM64 (aarch64) devices with an unlocked bootloader.
  • Root Solution: KernelSU or APatch are strongly recommended.
    • Magisk Incompatibility Notice: Magisk v29 and newer is explicitly unsupported due to changes in how pseudo-terminals (TTY/PTY) are handled in recent Magisk core builds. If running Magisk, you must stay on Magisk v28 or earlier.
  • Storage: At least 5–10 GB of free internal storage to house the extracted rootfs and installed software.

Architecture Constraints

The rootfs and pre-compiled binaries are built strictly for 64-bit ARM (aarch64). 32-bit ARM and x86 devices are incompatible.

Advanced Namespace Isolation

Unlike basic chroot implementations that simply restrict filesystem path roots, Ubuntu Chroot engages multiple Linux kernel namespaces:

  • Mount Namespace: Mounts created inside Ubuntu do not pollute Android’s /proc/mounts.
  • PID Namespace: Ubuntu processes receive isolated Process IDs, preventing accidental termination of Android system services during package installations.
  • UTS & IPC Namespaces: Provides independent hostname definitions and inter-process communication message queues.

Installation & Deployment

  1. Download the latest ubuntu-chroot release from the repository.
  2. Flash the module using KernelSU or APatch.
  3. Reboot your device to initialize kernel module hooks.
  4. Launch the WebUI:
    • In KernelSU / APatch: Open the WebUI directly from the module tile.
    • Or open a browser and navigate to http://localhost:8080 (or the port displayed in the manager).
  5. Follow the WebUI setup prompt to download and extract the base Ubuntu 24.04 rootfs.
  6. Module files and rootfs images reside in:
    /data/adb/modules/ubuntu-chroot/

Graphical Interface & Remote Access

Once the environment is running, access the graphical interface:

  • VNC Client: Connect any VNC viewer (such as AVNC or RealVNC) to 127.0.0.1:5901.
  • RDP (Remote Desktop): Connect using the Microsoft Remote Desktop app to 127.0.0.1:3389.
  • Default Credentials: The setup wizard guides you through setting your administrative Linux username and password.

Troubleshooting & Verification

  • Terminal TTY Errors on Magisk: If commands fail with openpty failed: No such file or directory or shell prompts exit immediately on Magisk, verify your Magisk version. Migrate to KernelSU or APatch, or downgrade Magisk to v28.
  • Docker Daemon Fails to Start: Running Docker containers inside the chroot requires specific kernel configs (e.g. CONFIG_CGROUP_DEVICE, CONFIG_OVERLAY_FS, CONFIG_NETFILTER_XT_MATCH_IPVS). Ensure your custom kernel includes modern containerization flags.
