{How To}Install Ubuntu Touch on Android Device

Ubuntu Touch is a touch-friendly interface based on the desktop Unity interface.

It is based on Qt and QML and various software frameworks originally developed for

Maemo and MeeGo such as oFono as telephony stack, accounts-sso for single sign-on,

[citation needed] and Maliit for input.The system can often be used with Linux kernels used in Android,

which makes it easily ported to most recent Android smartphones.

You can install the preview release of Ubuntu Touch on a Nexus device (the Galaxy Nexus, Nexus 4, Nexus 7, or Nexus 10).


PREPARE UBUNTU ON THE DESKTOP

To install the required software, open a terminal and run the following commands on your 

Ubuntu O/S
sudo add-apt-repository ppa:phablet-team/tools
sudo apt-get update
sudo apt-get install phablet-tools android-tools-adb android-tools-fastboot
