Requirements

• Download and install Ubuntu Installer Free to your phone from the Google Play Store.
• Enable USB Debugging on your phone by going to Settings > Developer’s options > USB Debugging
• Backup all personal data on your phone to make sure you have a copy of your personal data (e.g., contacts, SMS, MMS, Internet settings, Wi-Fi passwords, and the like) in case the procedure in this guide erases such data.

Instructions

1. Launch the Ubuntu Installer Free app. Launching the app will require you to download 3 additional apps:
   • android-vnc-viewer
   • Android Terminal Emulator
   • BusyBox
2. Download the Ubuntu image file via the Ubuntu Installer Free app. You will have to choose either the small or large Ubuntu image file.
3. You do not need to download the script suggested by the app because, according to tiborr, it doesn’t work with the Samsung Galaxy S3.  Download developer tiborr’s edited script (ubuntu.sh, 1.4 kB).
4. Using your preferred file manager app (e.g., ES File Explorer or ASTRO File Manager), navigate to your phone’s internal SD card and create a new folder named “ubuntu” (that is, /sdcard/ubuntu)
5. Extract the downloaded Ubuntu image file.  Move or copy the said file to /sdcard/ubuntu directory.
6. Move or copy tiborr’s ubuntu.sh script into the /sdcard/ubuntudirectory.
   • There should be an *.img file and a *.sh file inside the folder.
7. Open the Terminal Emulator app and enter the following commands:
   • su
   • cd /sdcard/ubuntu
   • sh ubuntu.sh
8. After a series of text, the terminal emulator will ask you to enter the screen size. Type 1280×720 and press Enter.
9. On the next screen, a message Save this as default? (y/n) will appear. Type the command Y if you want to save the screen size and N if you don’t want to save it as a default screen size.

10. The script may ask you to setup a password.  For our purposes, you can just use ubuntu as password.
11. The terminal will act as an Ubuntu command line. To connect to the graphical user interface (GUI), launch the androidVNC app.
12. Enter localhost on the IP address text field.
13. For port number, specify 5900 as the port number.
14. Enter ubuntu as password.
15. Leave all other fields as they are.
16. Tap Connect. The GUI will render and you will see the familiar Ubuntu interface.
17. To exit, return to the Terminal Emulator session, type exit at the command line, and wait until everything shuts down.

Alternative Method

If the steps above don’t work or the script isn’t working, you can try the alternative steps below:

1. Follow steps 1 and 2 from the procedures above.
2. Download this alternative script (ub.zip, 802 bytes).
3. Create a folder named “ubuntu” on your phone’s external SD card. The location should be /mnt/extSdCard/ubuntu.
4. Extract the downloaded Ubuntu image file and ub.zip to the ubuntufolder.
   • There should only be an IMG file and a SH file inside the ubuntu folder.
5. Open the terminal emulator and type the following commands:
   • su
   • cd /mnt/extSdCard/ubuntu
   • sh ub.sh
6. Follow step 8 and onwards from the procedure in the previous section.
