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 http://www.ubuntu.com/getubuntu/upgrading
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
