Install Ubuntu Touch on Nexus: Full Guide

Yes, you can install Ubuntu Touch on supported Nexus devices (Nexus 4, Nexus 5, Nexus 7 2013, and Nexus 10) using the official UBports installer. This guide walks you through the entire process, from checking device compatibility to booting into Ubuntu Touch, and covers common pitfalls.

What Is Ubuntu Touch and Why Install It on a Nexus?

Ubuntu Touch is a mobile operating system developed by the UBports community, designed as a free and open-source alternative to Android and iOS. It features a gesture-based interface, a full Linux shell, and convergence capabilities (using the phone as a desktop when connected to a monitor). Nexus devices are popular choices because they have unlockable bootloaders, active community support, and are officially listed as supported devices by UBports.

Prerequisites and Device Compatibility

Before starting, confirm your device is supported. The following Nexus models have official Ubuntu Touch support:

Nexus 4 (mako)
Nexus 5 (hammerhead)
Nexus 7 2013 (deb, flo)
Nexus 10 (manta)

Other Nexus models (e.g., Nexus 5X, Nexus 6P) are not officially supported and may have unstable or missing builds. You will also need a computer running Windows, macOS, or Linux, a USB cable, and a stable internet connection. Your device should have at least 50% battery to avoid interruption during flashing.

Backup Your Data and Unlock the Bootloader

Installing Ubuntu Touch replaces your current operating system, so back up all important data first. The process also requires an unlocked bootloader, which wipes the device. To unlock:

Enable Developer Options on your Android device (Settings → About Phone → Tap Build Number 7 times).
Enable USB Debugging in Developer Options.
Install the appropriate USB drivers for your device (Google USB driver on Windows, or use the built-in drivers on macOS/Linux).
Open a terminal/command prompt and run adb devices to verify your device is detected.
Run adb reboot bootloader to enter fastboot mode.
Run fastboot oem unlock (Nexus 4/5) or fastboot flashing unlock (Nexus 7/10). Confirm on the device screen.

After unlocking, the device will reboot and perform a factory reset. Re-enable USB debugging if needed.

Using the UBports Installer (Recommended)

The easiest method is the official UBports Installer, a graphical tool that automates the flashing process. Steps:

Download the UBports Installer from the official UBports website for your computer’s OS.
Install and launch the installer.
Connect your Nexus device via USB and put it in fastboot mode (if not already).
Select your device model from the dropdown list.
Choose “Ubuntu Touch” as the OS to install.
Click “Install” and follow the on-screen prompts. The installer will download the appropriate image and flash it automatically.

The process typically takes 10-20 minutes depending on your internet speed. Do not disconnect the device during installation.

Manual Installation via Command Line (Advanced)

If you prefer manual control or the installer fails, you can flash Ubuntu Touch using adb and fastboot commands. This requires downloading the correct system image for your device from the UBports CI or release page. The general steps are:

Download the Ubuntu Touch image (e.g., ubuntu-touch--.zip) and extract it.
Reboot into fastboot mode.
Flash the boot, recovery, and system partitions using fastboot flash boot boot.img, fastboot flash recovery recovery.img, and fastboot flash system system.img.
Wipe the data partition with fastboot format userdata.
Reboot the device.

Note: The exact partition names may vary by device. Consult the official UBports device documentation for the precise commands. Mistakes can brick your device, so only attempt this if you are comfortable with command-line tools.

Common Issues and Troubleshooting

Several problems can arise during installation:

Device not detected: Ensure USB debugging is enabled and drivers are installed. Try a different USB port or cable.
Installer stuck at “Waiting for device”: Reboot your device into fastboot mode manually (adb reboot bootloader) and try again.
Boot loop after installation: This often indicates a corrupted image. Re-download the image and reflash. Also, ensure you wiped the data partition.
No Wi-Fi or cellular connection: Some devices may require a manual configuration after boot. Check the UBports forum for device-specific fixes.
Touchscreen not responding: This is rare but can happen with unofficial builds. Reinstall the official image for your exact model.

Alternatives and Reverting to Android

If Ubuntu Touch does not meet your needs, you can revert to Android by downloading the factory image from Google’s developer site and flashing it with fastboot. The process is similar to unlocking: boot into fastboot, run fastboot flash boot boot.img, fastboot flash recovery recovery.img, fastboot flash system system.img, and fastboot flash userdata userdata.img, then reboot. This will restore your device to stock Android, but it will remain unlocked (you can relock it with fastboot oem lock if desired).

Other mobile Linux options include postmarketOS and Sailfish OS, but these have less mature support for Nexus devices compared to Ubuntu Touch.

Frequently Asked Questions

Will I lose all my Android data?

Yes, installing Ubuntu Touch wipes the device completely. Back up photos, contacts, and files before starting. The unlock process also performs a factory reset.

Can I run Android apps on Ubuntu Touch?

Ubuntu Touch does not natively run Android apps. However, the Anbox container can run some Android apps, but performance and compatibility vary. It is not a seamless experience.

Is Ubuntu Touch stable for daily use?

On officially supported Nexus devices, Ubuntu Touch is reasonably stable for basic tasks like calls, texts, and web browsing. However, some apps may be missing, and the app store is smaller than Google Play. It is not recommended for users who rely on specific Android apps.

Do I need to root my Nexus first?

No, you do not need to root the device. Unlocking the bootloader is sufficient. The UBports installer handles the rest.

What if my Nexus model is not listed?

If your device is not officially supported, you can try community builds, but they may be unstable or lack core functionality. It is safer to stick with supported models.

Will installing Ubuntu Touch void my warranty?

Unlocking the bootloader and flashing a custom OS typically voids the manufacturer’s warranty. Since Nexus devices are older and no longer sold officially, this is rarely a concern, but be aware of the risk.
