The Goal
Upgrading ubuntu using alternate ISO without having to burning it to the CD. We mount the ISO manually and install from there.
The Process
Important, upgrading an ubuntu require you to do it in sequence manner. For example, if your current version is Ubuntu 8.04 and you want to upgrade to Ubuntu 9.10 you must upgrade to 8.10 first, then 9.04 and finally 9.10. This tutorial cover upgrading from Ubuntu 9.04 to 9.10. So, here we go.
- Download ubuntu-9.10-alternate-i386.iso from one of download mirror.
- Save it to somewhere i.e. /home/abc/ubuntu-9.10-alternate-i386.iso
- Mount the ISO
$ sudo mount -t iso9660 -o loop /home/abc/ubuntu-9.10-alternate-i386.iso /media/cdrom0
- Execute the cdromupgrade script.
$ cd /media/cdrom0
$ sudo ./cdromupgrade &
- It's better to choose "No", and only fully upgrade from the iso.
- The upgrade process would start immediately.
- After all procress complete, restart your system.
- After logged in open the terminal and check the current Ubuntu version.
$ sudo lsb_release -a
Distributor ID: Ubuntu
Description: Ubuntu 9.10
Release: 9.10
Codename: karmic
- Enjoy your brand new Ubuntu :)

Ok, Thanks for sharing bro.. :D
i have choosen "no" for the 5. step but it still tries to download the packages from internet, i disabled my internet connection after and it says that because of my internet connection is down the update process is cancelled. I don't understand, i do everything to upgrade my 9.04 version to 9.10 with my 9.10 alternate iso but the stupid thing is it is still trying to download the packages from internet, and where is the benefit to download the iso from internet.
@Real Bezo,
That's strange behaviour, when you choose "No" ubuntu shouldn't use any network. Just make sure you disabled the network before executing "cdromupgrade" command.
