Title:
  do-release-upgrade prints misleading message

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed

Bug description:
  While running noble, after the oracular archive opening but before
  https://changelogs.ubuntu.com/meta-release-development being updated
  to include oracular, i.e., the meta-release-development file lists
  mantic and noble, I run:

  $ sudo do-release-upgrade -d

  And get the following output:

  Checking for a new Ubuntu release
  Upgrades to the development release are only 
  available from the latest supported release.

  /etc/update-manager/release-upgrades is set with "Prompt=normal".

  At this point, I would expect the upgrade attempt output to be more
  friendly. While I would not expect the tool to know we are in a
  corner-case state where there is a new active development release but
  the remote metadata file is not updated yet. However, I wonder if it
  should say something else instead, such as saying that there is no
  development release to upgrade to (since that is the case based in the
  information given by the metadata file).

  Note that, if I set /etc/update-manager/release-upgrades with
  "Prompt=lts" and run

  $ sudo do-release-upgrade -d

  I get the following output:

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

  Which is expected.
