How to install GUI on Ubuntu Server 12.04 from USB stick without internet connection

I take it you have ubuntu desktop on the usb. Or else you have to visit http://cdimage.ubuntu.com/ubuntu/releases/12.04/release/ and download the ubuntu-desktop image for the your architecture. And then create a boot usb.

Firstly you have to remove (or comment them by adding a # in front) all lines from /etc/apt/sources.list and /etc/apt/sources.list.d/* so you can call

sudo apt-get update
sudo apt-get dist-upgrade

Without getting any errors.

Once you have the usb connected you can add the deb src lines to /etc/apt/sources.list by using the apt-cdrom tool.

Description on how to use apt-cdrom can be seen here: https://help.ubuntu.com/community/AptCdrom

Basically it boils down to these commands.

sudo apt-cdrom ident 
sudo apt-cdrom -d "your-usb-mount-point" -r 

Once you have the correct apt lines you can must install the ubuntu-desktop package in order to get the gui.

sudo apt-get update 
sudo apt-get install ubuntu-desktop

Good luck!
