sudo do-release-upgrade

No new release found

sudo apt-get dist-upgrade

The problem is you are in a LTS version and 10.10 is a normal version.

Here are the steps:

Be sure that you apply all updates to your current version of Ubuntu before you upgrade:

sudo apt-get dist-upgrade

Now perform this procedure:

Network upgrade for Ubuntu servers (Recommended)

  1. Install update-manager-core if it is not already installed:

    sudo apt-get install update-manager-core

  2. Edit /etc/update-manager/release-upgrades and set Prompt=normal.

  3. Launch the upgrade tool:

    sudo do-release-upgrade

  4. Follow the on-screen instructions.

If I have to stop the do-release-upgrade process because of power failure or some other reason is there a way I can set back things to original – Registered User Sep 19 '13 at 12:29

Try sudo do-release-upgrade alone. If you are going to merge commands in one line, it should be like this:

sudo apt-get update && sudo apt-get dist-upgrade

Notice the two ampersands.

You broke the chaining of the two commands that were right (use && or just split them over two lines)

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