Installing Ubuntu Touch 16.04 images on Halium¶
These steps will wipe all of the data on your device. If there is anything that you would like to keep, ensure it is backed up and copied off of the device before continuing.
Now that you’ve built halium-boot, we’re ready to install Ubuntu Touch on your device.
In order to install Ubuntu Touch, you will need a recovery with Busybox, such as TWRP, installed on your phone. You will also need to ensure the /data partition is formatted with ext4 and does not have any encryption on it.
We’ll need to install the halium-boot image before installing an image. Reboot your phone into fastboot mode, then do the following from your Halium tree:
cout fastboot flash boot halium-boot.img
Download the rootfs¶
Next we’ll need to download the rootfs (root filesystem) that’s appropriate for your device. Right now, we only have one available. Simply download
ubports-touch.rootfs-xenial-armhf.tar.gz from our CI server. If you have a 64-bit ARM (aarch64) device, this same rootfs should work for you. If you have an x86 device, let us know. We do not have a rootfs available for these yet.
Install system.img and rootfs¶
Clone or download the halium-install repository. This repository contains tools that can be used to install a Halium system image and distribution rootfs. We’ll use the
halium-install script to install Ubuntu Touch on your device:
path/to/halium-install -p ut path/to/rootfs.tar.gz path/to/system.img
The script will copy and extract the files to their proper places, then allow you to set the phablet user’s password.
Get SSH access¶
When your device boots, it will likely stay at the bootloader screen. However, you should also get a new network connection on the computer you have it plugged in to. We will use this to debug the system.
To confirm that your device has booted correctly, run
dmesg -w and watch for “GNU/Linux device” in the output. If you instead get something similar to “Halium initrd Failed to boot”, please get in contact with us so we can find out why.
Similar to the Halium reference rootfs, you should set your computer’s IP on the newly connected RNDIS interface to
10.15.19.100 if you don’t get one automatically. Then, run the following to access your device:
The password will be the one that you set while running halium-install.
If you have any errors while performing these steps, check see if any of the following suggestions match what you are seeing. If you have installed successfully, skip down to Continue on.
