This may have been a temporary issues with dependencies in the development release. Please try upgrading again. Thanks in advance.

This bug was fixed in the package ubuntu-release-upgrader - 1:0.195

---------------
ubuntu-release-upgrader (1:0.195) saucy; urgency=low

  [ Dustin Kirkland ]
  * debian/release-upgrade-motd: LP: #1173209
    - recheck release upgrade once-a-day, even if stamp file is
      already populated
    - this partially fixes the sticky "upgrade available" message,
      after successfully upgrading, even if the stamp is not removed
  * DistUpgrade/DistUpgradeController.py: LP: #1173209
    - remove the upgrade-available flag, on upgrade completion
  * debian/ubuntu-release-upgrader-core.postinst: LP: #1173209
    - clear the upgrade-available flag, on postinst; it will automatically
      repopulate, if necessary

  [ Brian Murray ]
  * DistUpgradeCache.py: encode error message as UTF-8 (LP: #1177821)
  * DistUpgradeCache.py: double size estimate need in boot (LP: #1173468)
