I have tried to upgrade from the CD and by mounting the .ISO. However, all have been unsuccessfull.

I have downloaded the 32 bit version of 9.10.

I have tried to follow the instructions from this website

First I tried to mount the ubuntu-9.10-desktop-i386.iso using the following:

sudo mount -o loop ~/Desktop/ubuntu-9.10-desktop-i386.iso /media/cdrom0

Which mounted it. But I never got the dialog box that says 'run upgrade'

I then did 'Alt F2' and typed the following:

gksu "sh /cdrom/cdromupgrade"

Still nothing happened.

I can browse the files from the mounted *.iso and on the burnt CD. However, the dialog doesn't appear.

I can boot from the CD if I restart my computer. However, I just want to do a upgrade and not clean install.

I can't do an upgrade from the update-manager as my Internet is too slow and unreliable.

Many thanks for any advice

Did you try burning the ISO to cd and insert it into your cdrom instead of mounting the ISO directly? That should auto-mount the cd and pop up the upgrade dialog automatically. – cschol Nov 4 '09 at 4:57
Your gksu cmd is wrong. Correct syntax is: gksu "sh /media/cdrom0/cdromupgrade" – Blundell Jun 22 '11 at 10:42

As mentioned in the upgrade instructions, you need the alternate CD, ubuntu-9.10-alternate-i386.iso, to do the upgrade. Confusing, I know, but that's the way it works.

Here's a BitTorrent link:

You can also go to the download mirror listing at and get it from there instead.

I think you are right. I was thinking that the version I downloaded was able to start the upgrade. I didn't see anything to suggest that I have to download another iso. Thanks. – ant2009 Nov 4 '09 at 5:42
