| Once enough of the archive is built, any of your favorite methods for installing Ubuntu should work for ARM, if your device can boot from CDROM or USB.

| The primary differences are 1) Ubuntu uses "armel" as the architecture where mojo uses "arm" and 2) Ubuntu has a single architecture target where mojo may have several (e.g. armv5el-vfp vs. armv6el-vfp).

ARM Processor
ARM is a processor architecture used in a variety of applications, such as:
- Handheld Computers (Nokia n900, n95, etc.)
- Project development boards (Beagleboard, Pandaboard, Quickstart, etc.)
- Subnotebooks (Sharp Netwalker, etc.)
- Netbook/Notebooks (Toshiba AC100, etc.)
Ubuntu targets the ARMv7 and above Application Processor family (Cortex A8, A9 and above). Currently the archive supports ARM EABI, with an expectation of minimum compliance with the ARMv7+VFP ISA. Where possible Ubuntu targets the Thumb2 instruction set.
Limited support for earlier instruction sets (ARMv5t, ARMv6) was available in early releases of the ARM port (jaunty, karmic).
Status
- Much of the application porting is complete
- Installation images are available for selected boards
- kernels for a variety of sub-architectures are available
- Continued porting and optimization is underway

FAQ
Is Ubuntu validating low power server images
While there is no server class hardware available today work is being done to validate server loads so that when such hardware is ready, Ubuntu will be ready to run on it. See the Server page for information on this project.
How do i build an armel rootfs from scratch
Please see the Create a root file system from scratch page
How do I install Ubuntu on my device
For some devices, installation images are available from releases.ubuntu.com or cdimage.ubuntu.com For other devices, netinstalls are recommended, although this will require a custom kernel/debian-installer build for your target device. Please share your experiences with successful installs (and instructions) on the Device Support page.
How does this differ from Debian's armel port?
The primary difference is the ISA and instruction set targeted in Ubuntu, rendering nearly all packages incompatible at a binary level. As with the rest of Ubuntu, typically the source packages are identical, so most of the remaining differences are the same as differences generally between Debian and Ubuntu.
Where can I get help?
If it's ARM specific, stop by #ubuntu-arm on freenode. If it's not ARM specific, the regular Ubuntu support channels will provide better support.
What kernel flavours are available?
Available kernels have varied by release, as follows:
- lucid: dove, imx51, omap, versatile
- maverick: dove, omap, omap4, versatile
- natty: n900, omap, omap4, versatile
If you have a working kernel and wish to support it in Ubuntu, please contact the Ubuntu Kernel Team about configuration requirements and sponsoring procedures.
How can I help?
As a user: Try Ubuntu ARM on your device. Report any bugs to https://launchpad.net/ubuntu/+bugs. Report working hardware to ARM/DeviceSupport
As a developer: Try Ubuntu ARM for your use case. Fix anything that doesn't work. Submit the patches for upload. https://wiki.ubuntu.com/ARM/FTBFS
As a porter: Review applications not yet available for armel. Find out why. Port it, and submit the patches. Known issues are tracked at ARM/PortingIssues
- As a tester: Try following the Ubuntu test cases on an ARM device. Report any regressions from other architectures.
- As an author: Document installation procedures for various devices.
