You need to change prompt so that it is lts e.g. "prompt=lts".

Title:
  Upgrade from 12.04 to 14.04 fails

Status in “update-manager” package in Ubuntu:
  Incomplete

Bug description:
  The update-manager tries to update from 12.04 to 12.10 but this seems
  to fail, because it's no longer supported, instead it should update to
  14.04.

  Steps to reproduce:
  1. Buy a dell laptop with ubuntu 12.04 pre-installed
  2. Run sudo do-release-upgrade or update manager gui

  Current result:
   sudo do-release-upgrade
  Checking for a new Ubuntu release
  Err Upgrade tool signature
    404  Not Found [IP: 91.189.92.201 80]
  Err Upgrade tool
    404  Not Found [IP: 91.189.92.201 80]
  Fetched 0 B in 0s (0 B/s)
  WARNING:root:file 'quantal.tar.gz.gpg' missing
  Failed to fetch
  Fetching the upgrade failed. There may be a network problem.

  Expected result:
  Ability to upgrade to either 12.10 -> 13.04 -> 14.04
  or upgrade directly from 12.04 -> 14.04 a direct upgrade path seems better.

  Additonal information of affected system:
  lsb_release -a
  No LSB modules are available.
  Distributor ID:	Ubuntu
  Description:	Ubuntu 12.04.5 LTS
  Release:	12.04
  Codename:	precise
