You need a large-enough ext3fs partition created with Meta-Doctor mounted at /media/ext3fs (instruction how to create partition is available here [[Chrooting]]). Note that the latest optware bootstrap package will also use this if it exists. '''If you have not already done so you should setup the ext3fs partition to mount at bootup.''' (Failure to do so will cause you to run out of disk space) Instructions can be found on the [[Application:MetaDoctor#How_to_get_the_optional_ext3fs_partition_mounted_at_device_boot|Meta Doctor]] page.

Make sure you have the WebOS Internals Testing Feeds enabled.

Using Preware, install Xecutah and Ubuntu 11.04 Chroot.

Hit the relevant buttons on Xecutah to run the XServer and the Ubuntu 11.04 Chroot.

Run XServer first, which will open an Xserver window, then return to Xecutah and tap Ubuntu 11.04 Chroot. When you return to the Xserver card, you should see a Ubuntu command prompt.

Use "apt-get install" to install whatever apps you like from Ubuntu. Then run in the Ubuntu chroot and render on the XServer.

Don't forget the donation link on the Main Page, and please install the Preware Homebrew Documentation app from the official app catalog to learn how to install Preware on your device.

<center>'''NOTE ABOUT DISK IMAGES'''</center>
It is possible to use a disk image instead of creating a partition. However, this comes with a few caveats, such as slower speed, disk size restriction (mounting a disk image in cryptofs may limit you to < 2GB) or breaking USB connectivity (on /media/internal). Do this at your own risk. '''Partitioning with Meta Doctor is the faster and slightly stabler method.'''

If you do not want to re-doctor your phone, this is how to do it with an image file:
First, open a terminal (XServer >XTerm - everything is done on device).

1048576 (KB) means 1 GB, you can replace that (used in two commands). NOTE: You can not create an image file in /media/cryptofs larger than 2GB.

cd /media/cryptofs
dd if=/dev/zero of=ubuntu.img bs=1024 count=1048576
mkfs.ext3 -F -b 1024 ubuntu.img 1048576

mkdir /media/ext3fs

Next, you must mount the new image file.

mount -o loop /media/cryptofs/ubuntu.img /media/ext3fs

Now you can install Ubuntu 11.04 Chroot from Preware and it will populate the image file.

Make sure you have the WebOS Internals Testing Feeds enabled. And remember that at this time, you will either need to have installed the Developer Beta Firmware of have access to a Bluetooth Keyboard. No virtual keyboard is available.

Do this at your own risk. '''Partitioning with Meta Doctor is the faster and slightly stabler method.'''

With those caveats in mind, if you decide to go ahead and create an image file, you can download a basic image file(debsmall.img.bz2) here [http://www.public.iastate.edu/~7Emdklein/debsmall.img.bz2]

Extract debsmall.img from debsmall.img.bz2 (use 7zip in windows or the bunzip2 from command line in linux) and copy it to your device. You can use WOSQI to send the file to /media/cryptofs. Using /media/cryptofs instead of /media/internal will avoid breaking USB connectivity.

Then using the WOSQI command line, resize the file: “resize2fs /media/cryptofs/debsmall.img 2000M” (must be less than 2048M).

Next, you must mount the new image file. Since, when using an image file, you may have to mount it again each time you do a full restart of the device (the image will stay mounted after a luna restart), you may want to create a script:

Using a text editor copy the following into a file and copy it to the device as, e.g., "/media/internal/mountscr.sh". (note that when using a program such as windows notepad, your line breaks may not stay in place correctly.)

#!/bin/sh
mount -o loop /media/cryptofs/debsmall.img /media/ext3fs
mount --bind /dev /media/ext3fs/dev
mount -t devpts none /media/ext3fs/dev/pts
mount -t proc none /media/ext3fs/proc
mount -o bind /tmp /media/ext3fs/tmp

Then, from the WOSQI command line, type "sh /media/internal/mountscr.sh".

Now you can install Ubuntu 11.04 Chroot from Preware and it will populate the image file.
