I need to upgrade my existing Ubuntu system, and I also want to install Ubuntu on a new laptop. I would like to have an installation CD or DVD to do both of these. Where exactly I can order or request an Ubuntu installation CD/DVD/USB?


You can Buy Ubuntu Desktop DVD from OSDisc.com website.

You can also obtain the Full Ubuntu Software Repository (11 DVDs) from there site or You can directly go to the page by clicking here.

Please Remember that, You must pay for their products. If you do not need all of the software from the repository, It probably be costly for you.

    Full repository, Nice! that would be great for no Internet. – Mateo May 13 '12 at 17:46

It's no longer possible to request a CD with the "Ship-it" service. You now have to download it, or order it from a third party company or via the Canonical Store.

An 8GB bootable USB stick of Ubuntu 16.04 LTS Desktop is available from the official Canonical Store for $7.29.

enter image description here

Update: Canonical is no longer producing bootable USB/CDs and neither is any other source that I regard as reliable (better than eBay).

Buying a blank 4GB 8GB USB flash drive is cheaper than buying an Ubuntu USB. It only costs about $5.00 USD. A USB flash drive is reusable, and you can download whatever version of Ubuntu you want, and then use the flash drive as an Ubuntu installation disk.

How to make bootable Ubuntu live USB


The instructions for preparing an Ubuntu live USB on Windows are found at the official Ubuntu How to create a bootable USB stick... webpage (see the step-by-step instructions below). The USB flash drive that you use to make an Ubuntu live USB must be 2GB or larger. For Ubuntu 18.04 and later the USB flash drive should be 4GB or larger.

  1. Open Rufus and select your USB stick in the Device dropdown menu.

enter image description here

  1. Click the CD-ROM icon next to the FreeDOS dropdown menu, then find your downloaded Ubuntu ISO and click Open and then Start.

enter image description here

  1. Click Yes when it asks to download Syslinux software.

enter image description here

  1. Click OK to write in ISO Image mode.

enter image description here

  1. Confirm that your USB stick is selected and then click OK to continue. It is very important to verify that the device that you are installing the Ubuntu live USB to is indeed your flash drive, so that you don't overwrite any of your system or personal files which may make your operating system unbootable.

enter image description here

  1. When it is finished, just restart your computer and start using Ubuntu, or you can install Ubuntu.

enter image description here

In order to enable your computer to boot from the USB flash drive, you must enter your BIOS/UEFI setup utility by pressing one of these keys: Delete, F2 or F10 as soon as the motherboard splash screen appears when the computer is booting. In the BIOS/UEFI menu, you need to change the boot order so that the USB flash drive, which is usually called USB-HDD in newer computers, is the first entry in the boot sequence, and then save your new settings and exit the setup utility.


This procedure requires that you create an .img file from the .iso file you download. It will also change the filesystem that is on the USB stick to make it bootable, so backup all data before continuing.

  1. Download Ubuntu Desktop

  2. Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight).

  3. Insert your USB flash media, which must be 2GB or larger. For Ubuntu 18.04 the USB flash drive should be 4GB or larger.

  4. Launch the Disk Utility app which is located in Applications -> Utilities. Booting Ubuntu from the USB drive

  • In the lefthand pane, click on the USB drive to select it.
  • Click the Partition tab.
  • Select 1 Partition from the dropdown menu.
  • Enter a name for the drive.
  • Change the Format to Mac OS Extended (Journaled).
  • Click the Options button.
  • Ensure that the GUID Partition Table radio button is selected and click OK.
  • Click Apply.
  1. Convert the .iso file to .img using the convert option of hdiutil e.g.,

     hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso

    Note: OS X tends to put the .dmg ending on the output file automatically.

  2. Run:

     diskutil list

    to get the current list of devices.

  3. Run:

     diskutil list

    again and determine the device node assigned to your flash media (e.g. /dev/disk2).

  4. Run:

     diskutil unmountDisk /dev/diskN

    (replace N with the disk number from the last command; in the previous example, N would be 2).

  5. Execute:

     sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m

    (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg).

  • Using /dev/rdisk instead of /dev/disk may be faster
  • If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M
  • If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start the 'Disk Utility.app' and unmount (don't eject) the drive
  1. Run:

    diskutil eject /dev/diskN

    and remove your flash media when the command completes.

###Booting Ubuntu on a Mac from the USB drive

The newly created Ubuntu live USB drive is now ready to be inserted into a Mac.

Booting Ubuntu from the USB drive

To test the Ubuntu live USB on a Mac:

  1. Insert the USB drive into an available USB port.
  2. Reboot or turn on the Mac.
  3. Immediately after the startup chime, press the Option key (sometimes marked Alt).
  4. Select the USB drive from which to boot by using the left and right arrow and Enter keys.
  5. If you can't see the USB drive in step 4, download rEFIt EFI Boot Menu and Toolkit to get a screen where you can choose from the available devices to boot from.

You should try downloading an ISO image from http://www.ubuntu.com/download. This page describes how to burn the downloaded ISO to a disk after you obtained it.

Install apt-offline pkg:

$ sudo apt-get install apt-offline
  1. Generate “apt signature” file:

     $ sudo apt-offline set ~/my.sig
  2. Download the required packages:

    Once you have the .sig file on a USB drive, connect it to an internet connected computer running on Ubuntu and use the following command in the terminal:

     $ apt-offline get -d /to_any_chosen_directroy /path_to/apt.sig
  3. Install the downloaded packages:

     $ sudo apt-offline install /path_to_downloaded_package_folder

Enjoy the latest updates.


You can use command-line to upgrade:

$ sudo apt update 
$ sudo apt upgrade
$ sudo apt dist-upgrade


$ sudo apt autoremove

Now follow below steps to upgrade:

$ sudo apt install update-manager-core
$ sudo do-release-upgrade -d

After install you should change source list:

$ sudo sed -i 's/xenial/bionic/g' /etc/apt/sources.list

Now you upgrade to 18.04

After all:

$ sudo apt update && sudo apt -y dist-upgrade

You do not need to buy a disc.

Just download the ISO and burn it to a DVD.

You can buy Ubuntu on Ebay (cheapest) - a DVD with international shipping is about US$5, USB flash drives are around $10.
