Thanks for the reply.

I just typed it here and made a typo.

 From /etc/update-manager/release-upgrades

# Default behavior for the release upgrader.

# Default prompting behavior, valid options:
#  never  - Never check for a new release.
#  normal - Check to see if a new release is available.  If more than 
one new
#           release is found, the release upgrader will attempt to 
upgrade to
#           the release that immediately succeeds the currently-running
#           release.
#  lts    - Check to see if a new LTS release is available.  The upgrader
#           will attempt to upgrade to the first LTS release available after
#           the currently-running one.  Note that this option should not be
#           used if the currently-running release is not itself an LTS
#           release, since in that case the upgrader won't be able to
#           determine if a newer release is available.
