On December 23, Canonical surprised us all with a gift for Christmas in advance, announced Dual boot Ubuntu and Android to developers, and thus we offered an alternative operating system to test Mobile, Ubuntu Touch , without having to give up our fully functional version of Android.

Bitelia and we explain step by step how to install Ubuntu Touch 1.0 on Nexus devices supported, at that time we can install without problems on a Nexus July 2012, and we take a look at Ubuntu promise Tablets and smartphones . Although the experience still feels very raw, this time we have to leave our basically useless device if you want to try Ubuntu, but we can be constantly updated versions to go seeing improvement, and also use our Android device normally.

To help you do this, we have created this simple guide, step by step to teach you how to easily install Dual Boot Ubuntu and Android on your device.

Requsitos:

1. One of the devices officially supported, see full list.
2. Android 4.2 or higher, stock or based on CyanogenMod or AOSP.
3. 2.7GB of free space to install Ubuntu touch.
4. Bootloader unlocked.
5. Ubuntu installed on the computer or a derived distribution.

Win

6. and patience.

 adb kill-server

And then:

 adb start-server

To verify that your device is being recognized by the system, type in the terminal:

 adb devices

Before continuing, we can make a backup of our system in case something bad happens, (this step is optional, but doing backups is never more if things go the demon). To make a backup of your Android to your computer, type in the terminal:

 adb backup-apk-shared-all

Pet

The device will reboot several times, and at the end you have to find on your list of applications: "Ubuntu Dual Boot". Important not to intervene in the facility at any time, although it seems that nothing happens.

Install Ubuntu from Android

Since we have

list function Dual Boot, Touch now can install Ubuntu. Recall that for this we will need 2.7 GB of free space, before we can continue cleaning the cache Android quickly with a command to retrieve a bit of space:

 adb shell "your sh rm-rf / cache / *"

Android

When the command request superuser permissions allow.

now on our list of applications look for the icon of Ubuntu Dual Boot and pressed.

When the application starts, pressed Choose channel to select a channel and start downloading Ubuntu, the preferred channel is Trusty, and is automatically selected. Now we only hope that the image is downloaded.

Once the download is complete, you must grant superuser permissions to the application to complete the installation. Now you can press the button Reboot to Ubuntu to reboot into Ubuntu.
