I've just tried to upgrade my ubuntu 8.04 to 8.01 using the alternate cd.
I downloaded the cd image and mounted in using the command given on the ubuntu upgradation site but nothing happened.
"sudo mount -o loop ~/Desktop/ubuntu-8.10-alternate-i386.iso /media/cdrom0"
I also wrote the image to a cd,inserted it.Still no dialogue asking me to upgrade.
I've also tried using the alternate command after pressing alt+f2
"gksu "sh /cdrom/cdromupgrade""
It opens a "starting administrative task" window in the bottom desktop panel.then it goes upto asking my password and when I enter it the comp returns to normal as if nothing had happened.
I'v tested the cd for defects by booting from it and also run a live session from it.
Please help.
