It is easy to upgrade from Ubuntu 9.04 to Ubuntu 9.10.
- Start the Update Manager: Press Alt+F2 and type “update-manager” without quote.
- If your computer is not up-to-date, hit the Install Updates button to update all of the outdated packages.
- After the packages update is done, hit the Check button, this will cause Ubuntu to check for updates again.
- Ubuntu 9.10 distribution release will appear => click on the Upgrade button to begin.

- Follow the screen…
- Once the upgrade is complete and it asks to remove obsolete packages, click on Remove.
- To complete the upgrade, click on the Restart button. You should now be on Ubuntu 9.10. To verify, start the Terminal and type:
sudo lsb_release -a
Upgrade from a CD or iso file:
If you would like to perform the upgrade for a computer that does not have access to the Internet, you would need to download the Alternate ISO copy, not the normal download copy found on ubuntu.com.
You can obtain the Alternate ISO version from here: http://mirrors.kernel.org/ubuntu-releases/9.10/
Installation Instructions:
- Boot up your Ubuntu
- Once your computer is ready, insert the CD
- A dialog will be displayed => click on Run upgrade to begin

Besides burning Ubuntu to a CD, you can also perform the upgrade directly from the .iso file. Here is the command to mount the .iso file:
sudo mount -o loop ~/Desktop/ubuntu-9.10-alternate-i386.iso /media/cdrom0
Now start the upgrade process:
gksu “sh /cdrom/cdromupgrade”

what tha _. Now they tell me… I’ve spent two days downloading the wrong ISO. they really have to put a big sign somewhere, is it possible to do a migration? i.e install a new partition, import stuff from the old installation then format the old partition then use gparted to resize the new partition to fill the remaining space?
But then again I’m sure it was my fault for not doing my research, sigh another two days…
Edit: between this sentence and the last, I’ve downloaded 20MBs already. The torrent system seems much much much faster than HTTP. for me anyway. but just out of interest do you think my previous idea would have worked? he he

Hi Faisal,
Please follow the Upgrade from a CD or iso file section above.
I am having a problem with the upgrade. I can not find the dialog box appearing. Also, my update manager says nothing about the newer version available also when I have inserted a CD.
I put the ubuntu 9.10 server CD in the PC. But an error is comming and the message displayed is:Kermic error ‘the Cd is not genuine. The CD is being send by UBUNTU from The Netherlands. Please help me
