Ubuntu 14.04 LTS on Radxa Rock

currently only very first part is written... ;)


first of all, install miniroot.

prepare miniroot

network (DHCP)

miniroot# udhcpc

network (static)

miniroot# ip addr add broadcast + dev eth0
miniroot# ip link set dev eth0 up
miniroot# ip route add default via
miniroot# echo nameserver > /etc/resolv.conf

replace 192.168.1.* with correct addresses for your network.


you can use any supported storage, partition, and (sub)directory.

e.g. make ext4 file system on first partition of external SD card, then mount it on /mnt

miniroot# mkfs.ext4 -E nodiscard /dev/mmcblk0p1
miniroot# mount /dev/mmcblk0p1 /mnt


ubuntu-core is minimal root file system. you can setup desktop or server environment after install.


miniroot# wget -P /mnt http://cdimage.ubuntu.com/ubuntu-core/releases/trusty/release/ubuntu-core-14.04.3-core-armhf.tar.gz


extract tarball (e.g. under "ubuntu" directory on external SD card)

miniroot# mkdir /mnt/ubuntu
miniroot# tar -xpzf /mnt/ubuntu-core-14.04.3-core-armhf.tar.gz -C /mnt/ubuntu

setup sources.list

miniroot# wget -P /mnt/ubuntu/etc/apt http://files.androtab.info/radxa/ubuntu/sources.list

setup hostname (e.g. "ubuntu")

miniroot# echo ubuntu > /mnt/ubuntu/etc/hostname
miniroot# sed -e 's/miniroot/ubuntu/' < /etc/hosts > /mnt/ubuntu/etc/hosts

setup serial console (automatically log-in as "root")

miniroot# sed -e 's/tty1/ttyFIQ0/g' -e '/^exec/c exec /sbin/getty -a root -L 115200 ttyFIQ0 vt100' < /mnt/ubuntu/etc/init/tty1.conf > /mnt/ubuntu/etc/init/ttyFIQ0.conf

if you cannot use serial console, you must setup user account here. (e.g. user "ubuntu" password "ubuntu")

miniroot# chroot /mnt/ubuntu useradd -G sudo -m -s /bin/bash ubuntu
miniroot# echo ubuntu:ubuntu | chroot /mnt/ubuntu chpasswd


miniroot# boot /mnt:/ubuntu

you can specify path of root device in 1st argument if it's not mounted. (e.g. "boot /dev/mmcblk0p1:/ubuntu")

initial setup

setup network (e.g. DHCP)

root@ubuntu:~# echo auto eth0 > /etc/network/interfaces.d/eth0
root@ubuntu:~# echo iface eth0 inet dhcp >> /etc/network/interfaces.d/eth0
root@ubuntu:~# ln -fs ../run/resolvconf/resolv.conf /etc/resolv.conf
root@ubuntu:~# ifup eth0

update packages

root@ubuntu:~# apt-get update
root@ubuntu:~# apt-get dist-upgrade


root@ubuntu:~# reboot


change miniroot configuration

miniroot# editenv
miniroot# saveenv
miniroot# reboot -f

prepare desktop environment

root@ubuntu:~# apt-get install lubuntu-desktop
