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. –  david6 Dec 11 '12 at 20:10
Note it is fine to do this for 13.04 to 13.10 etc. –  Wilf Jan 28 at 17:33

  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"
