How to make a dedicated Unity USB Stick

This is a way to make a USB key with Ubuntu prereleases installed on it that you can update every day and not have to break your existing install.

Step 1: Download the latest Daily Natty image

Go to this page and download an ISO for your computer. It should be saved to the Downloads directory on your computer.

Step 2: Create the USB stick installation

Click Applications -> System -> Startup Disk Creater. It looks like this:


When you start the application, it will likely automatically find the ISO you downloaded, which is displayed in the top pane. If you don’t see it, click the Other button and go and select the ISO (typically in your Downloads/ directory in your home directory).

It is recommended you first erase your USB stick, so select it in the bottom pane and click the Erase Disk button. When this is complete, you can then use the slider underneath the Stored in reserved extra space slider to select how much disk space can be used for saving files, documents and other things. I personally move the slider all the way to the right to use the maximum space available.

Finally, click the Make Startup Disk button and Natty will be installed to your USB stick.

Step 3: Boot into the Key

Now you need to boot from USB stick. To do this you may need to enter your BIOS to enable your computer to be able to boot from the USB stick. When this is enabled you will typically need to hit a button when you boot to see the BIOS’s boot menu (e.g. on my Thinkpad T400 it is F12) and then you can select the USB drive.

Ubuntu should boot and look and function the same as usual, apart from being much slower as you are running from the USB disk.

Step 4: Update and Prepare the Key

Although you installed the latest daily you should ensure it is up to date, and you can do this with:

sudo apt-get update
sudo apt-get upgrade

From now on you can update the key daily to keep it up to date. Now you need to enable apport so that when something crashes it can report it to Launchpad:

Edit /etc/default/apport, set and set enabled=1.

Step 5: Test and Report Bugs

Although Natty is still very much in the early stages of development, we want to know when you experience bugs. If we don’t know about the bugs our community can’t fix them!

Since the key can be updated you merely need to update it before you are ready to test and then try it on as many pieces of hardware that you can find. Since apport is set to report crashers you can quickly start finding hardware bugs.

Many of you will be particularly interested in testing Unity, and we are really keen to hear about bugs and problems in Unity. Filing a bug is simple. Just open a terminal and run:

ubuntu-bug unity

The ubuntu-bug program zips up some debugging data from your system and will then fire up a page in your browser where you can enter a bug report. This will then provide details of the problem to the Unity developers to help fix the bug.

For Developers: Installing a Development Environment

Install these packages if you want a Unity development so you can start fixing bugs! Here's a list of easy bugs to get you started.

sudo apt-get install bzr build-essential 
sudo apt-get build-dep unity

That command will get you all the development tools you need, after that you'll have everything you need to update the USB key every day and start hacking on Unity. Now just follow these instructions to grab the code and rock it!
