I'm using Ubuntu 10.04 now and want to Upgrade to Ubuntu 11.04. The problem is my net connection is very slow and I can not do a network upgrade from the "Updates Manager".

So, is there a way that I can download the Ubuntu upgrade as an bootable CD image and upgrade from it?

    UPDATE: It is strongly recommended to not attempt to upgrade in this manner, skipping intermediary releases. Upgrades to 10.04 LTS should be only to 10.10 (no longer supported), or directly to 12.04 LTS.

  • did you try burning the iso onto a disk then loading it into your dvd drive and installing it from their, after booting from dvd drive once the iso is burned onto disc?

  • is it absolutely necessary for you to upgrade via the iso? the software centre provides a decent and safe manner of upgrading without ruining your existing installation

    Actually my internet connection is not stable and it may be disconnected in the middle of the process. But I got the ISO using a download manager. Commented Nov 2, 2013 at 7:20
  • More over it would be very useful for enterprises which may have more than one instance of Ubuntu to upgrade. Commented Nov 2, 2013 at 7:23

  1. Download the alternate installation CD
  2. Burn the ISO to a CD and insert it into the CD drive of the computer to be upgraded. If the ISO file is on the computer to be upgraded, you could avoid wasting a CD by mounting the ISO as a drive with a command like:
sudo mkdir -p /media/cdrom  
sudo mount -o loop ~/Desktop/ubuntu-11.04-alternate-i386.iso /media/cdrom

(make sure you use the actual filename of the iso you downloaded ^^^^ )

  1. A dialog will be displayed offering you the opportunity to upgrade using that CD.
  2. Follow the on-screen instructions.

If the upgrade dialog is not displayed for any reason, you may also run the following command using Alt+F2:

gksu "sh /media/cdrom/cdromupgrade"

Or if you're using Kubuntu run the following command using Alt+F2:

kdesudo "sh /media/cdrom/cdromupgrade"

    This way, can we upgrade latest versions of Ubuntu like 14.x 16.x ?

Just make a bootable USB or CD/DVD and boot it up as you would install ubuntu. When you are asked what you want to do just select "Upgrade...": Option

  • In the question I have mentioned that I don't want to use usb or cd fro this purpose.

    How does this differ from 'do-release-upgrade'? I say this because I'd like to upgrade a release by CD without loosing any programs or settings for a computer that is off the grid. In my experience using the upgrade as you have suggested was never better than with 'do-release-upgrade'.

  • Was the "upgrade" feature removed from latest live ISO? It was not displayed when I tried to upgrade my broken installation askubuntu.com/questions/1085665/…

Okay, so since cdromupgrade file is missing or not available, the next best thing is to create a LiveUSB and go on from there. Since you're upgrading from 13.04 the entire process should be rather flawless.

  1. Open the Dash and open the *Create Startup Disk * option. This opens a window, from where you can choose the iso file and destination.
  2. Now select the 13.10 iso file and a usb (remember to use the erase disk option before you mount the image) and create your startup disk.
  3. Now, upon re-booting you should boot directly into the USB. Select the install Ubuntu 13.10 option.
  4. The installer window would present a number of options to you depending on the other OSes present in your hard drive.
  5. Choose the Upgrade to 13.10 option. This should get you going and ready for 13.10.

Hope this helps you.

  • I got org.freedesktop.UDisks.Error.Inhibited: Daemon is inhibited error when I want to erase the usb drive. Commented Nov 2, 2013 at 9:17
  • is it mounted? please make sure that it is not mounted.

  • I'm commenting from 13.10 thanks for your help but I think using the software updater would be better. Commented Nov 2, 2013 at 17:32
  • It would be, the system is designed to handle all sorts of dependencies. But as long as you have a clean install of 13.10, its okay. Have fun using 13.10! :)

  • Good to see that the LiveUSB worked for you @A.Karimi. It did for me too, because I had similar issues with having a stable internet connection. Also, it will prove to be useful, as you rightly suggest, for installation on multiple systems.

You can boot ISO files from Grub. However, I think you will need to have the ISO file on another medium (such as another hard drive, or a USB/CD/DVD)

Booting from Grub2: https://help.ubuntu.com/community/Grub2/ISOBoot

Installing over the network: Is it possible to install Ubuntu through network?

And finally: https://help.ubuntu.com/community/Installation#Installation_without_a_CD

Though if you have your /home in a separate partition (or any other non-standard filesystem configurations like that), this will not work.... You must reinstall, rather than upgrade.

Though you can simple upgrade incrementally through the normal method:

http://www.ubuntu.com/download/desktop/upgrade though you may have to check your settings.
