I am using Ubuntu 12.04 server and I would like to place that PC for testing purposes so moving to 12.10 server but I am unable to do that. I am doing this in a VM, so I can't copy/paste the text report. I took a screenshot instead.

I have done:

sudo apt-get install update-manager-core
sudo do-release-upgrade -d

enter image description here

What am I doing wrong?

check /etc/update-manager/release-upgrades maybe prompt value is lts where it should be normal

Sorry for late , I am just busy with usual works . – Raja Oct 16 '12 at 13:24

Could whatever mirror your packages get update from (in /etc/apt/sources.list) not contain the current beta release? You could try using a different mirror.
