Now it's easier to test Ubuntu on the phone, and you can download a program from canonical that installs the new operating system without deleting the original Andorid. A dual-boot system can attract more users to focus on the new open source platform on the phone/tablet.
Canonical has a process on its website that explains how to install Ubuntu on the phone, but it actually requires removing the Android system to get a new operating system. The Ubuntu developer has done a lot of work and the new system looks great, but if you decide to go back to Android, you'll need to remove Ubuntu and install Google's Android system. This means that you have to repeatedly set up your phone, which may be more cumbersome.
Fortunately, there is now a solution called Multirom Manager, developed by Vojtech Bocek, which can now be downloaded from Google Play, and supports Nexus 7 (& 2013), Nexus 4, and Nexu S 5.
On the other hand, the Ubuntu touch only supports Nexus 4 (Mako), Nexus 7 (2013) Flatbed (FLO) and Nexus 10 flatbed (Manta), so unless you have these devices, you may not be able to perform these steps safely (it may work, but not guarantee will make your device brick at the same time/or lose all the data. )
First, you need a unlock device, and since you have a Nexus device, this should not be a problem. You also need to root your andorid device so that you can install the operating system in this application.
There are a lot of tools to do this root work. First, you need to install the ADB (Android Debug Bridge), which accompanies Canonical's tools. You need to run the following command under the terminal:
sudo add-apt-repository ppa:phablet-team/toolssudo apt-get updatesudo apt-get Install

Now you need to download two binary packages, TWRP 2.7.0.0 and Supersu, which will allow you to implement root. Copy Supersu's binary zip package into your phone's memory and run the following command into Bootloader (the original command sudo reboot bootloader, which should be a clerical error lost adb command):
sudo adb reboot bootloader
Unzip the TWRP file on your computer and install it on the phone with the following command (replace "recovery.img" with your downloaded filename) (the fastboot here should also need sudo permission to execute.) )
sudo fastboot flash recovery recovery.img
Enter recovery from the bootloader menu and you will see TWRP 2.7.0.0. Run TWRP and install the Supersu binary package, then reboot.
Now you have root access. Install multi Manager, apply patches, and download Ubuntu for your phone. The application will require root permission, and the installation will proceed smoothly. When you reboot you will see a small window that prompts you to select the system you want to run. After you choose Ubuntu, you can run it.
Is it a new enjoyment?
