Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS develoment release
set Prompt=normal in /etc/update-manager/release-upgrades.

# Default behavior for the release upgrader.

[DEFAULT]
# Default prompting behavior, valid options:
#
# never - Never check for, or allow upgrading to, 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 supported 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 if this option is used and
#      the currently-running release is not itself an LTS release the
#      upgrader will assume prompt was meant to be normal.
#Prompt=lts
