== How to get the Ubuntu distribution ==
The Ubuntu project is excited to be working with the ARM ecosystem to port Ubuntu for ARM-based devices. This work fits with our goals of making Ubuntu available as an open platform to as many people as possible. Some points to note:
=== Overview of How-To =Requirements==This How-To is meant to be a starting point for people to learn install an Ubuntu image for IGEP v2 devices as quickly and easily as possible.* A SD card at least 2GB ( recommended 4GB )
==Ubuntu releases=== Feedback and Contributing =Releases==At any point, if ['''TIP'''] If you see a mistake want to install the ubuntu image you can contribute to this How-Toshould install the ubuntu rootfs and use the ISEE kernel and bootloader.
['''IMPORTANT'''] ISEE is not responsable about the Ubuntu releases you should read the information about Ubuntu deprecation releases in the Ubuntu webpage. === References Ubuntu 12.04.4 LTS (for IGEPv2, IGEP COM MODULE ISEE devices)===Much IGEPv2, IGEP COM Module and IGEP COM Proton Ubuntu page is located [[IGEPv2 Ubuntu Distro|here]] ===Ubuntu 12.04.4 LTS Hard Float (for IGEPv5)===IGEPv5 Ubuntu page is located [[IGEPv5 Ubuntu Distro|here]] ===Ubuntu 14.04 Lxde (for IGEP iMX6)===IGEP iMX6 Ubuntu page is located [[IGEP iMX6 Ubuntu Distro|here]] ===Ubuntu Base Firmware (All Boards)===Ubuntu base page is located [[IGEP Firmware Ubuntu|here]] ==Old Releases=====Ubuntu 10.10 (Maverick Meerkat)===First, download the compressed image from http://cdimage.ubuntu.com/ubuntu-netbook/ports/releases/ wget http://cdimage.ubuntu.com/ubuntu-netbook/ports/releases/maverick/release/ubuntu-netbook-10.10-preinstalled-netbook-armel+omap.img.gz Next, uncompress the image with gunzip ubuntu-netbook-10.10-preinstalled-netbook-armel+omap.img.gz Then write the raw image to a blank SD card (the card size should be >2G) sudo dd if=<uncompressed image> of =/dev/mmcblk0 # change /dev/mmcblk0 with appropriate device Current boot file system (x-loader + u-boot + kernel) not works, so we need to replace.

====Make a bootable MMC card on Linux====
Thanks to Graeme Gregory and Steve Sakoman, you can now use [http://www.sakoman.com/OMAP3/a-script-for-partitioningformatting-a-bootable-sdmicrosd-card.html a script to automate the tedious process of creating a bootable SD/microSD card.]
Having followed this excellent tutorial it's time to mount your SD card boot partition (/media/boot). With your preferred editor create a boot-ini.source file like this.
The result will be a boot.ini file which you will copy to SD card boot partition
$ cp boot.ini /media/boot === Getting =Get a copy of a ARM ubuntu root file system ====In order to get a copy of a ARM ubuntu root file system, you will need to install qemu and a recent version of debootstrap and the qemu package. On some systems you may also need the qemu-kvm-extras package to run the ARM emulation.
Next, you will download a helper program to build the rootfs
The following example will create a tarball of ubuntu-desktop based image for your target device:
Typical images (example settings):
To build a xubuntu-desktop image use the following options:
--imagesize 2G --seed xubuntu-desktop
For an ubuntu-desktop image (a similar size is needed if you want a kubuntu image):
--imagesize 3G --seed ubuntu-desktop
A typical remote development comandline environment if you run an armel board headless (note that you should edit /etc/network/interfaces and set up your network device on first login for this):
--imagesize 3G --seed build-essential,openssh-server
A very light desktop (lxde):
--seed lxde,gdm
Next, mount your SD card ext3 partition (/media/rootfs) and untar the rootfs
Finally, umount the SD card, insert the card in your board and power up.
