Title:
  Dist-upgrade failed: 'The package 'postgresql-12' is marked for
  removal but it is in the removal deny list.'

Status in ubuntu-release-upgrader package in Ubuntu:

Status in ubuntu-release-upgrader source package in Noble:
  Fix Released

Bug description:
  [Impact]

  In general, when an upgrade fails because of a denied package removal
  (due to matching entry in the package removal denylist), the upgrade
  is aborted without a user-facing / friendly message.

  If a user installed a system with e.g. 20.04 and installed
  postgresql-12, then upgraded to jammy without removing postgresql-12,
  and then later attempts to upgrade to noble, the upgrade will fail
  because apt will calculate that postgresql-12 needs to be removed in
  order to satisfy all other deps.

  Hence, users in this situation will have a failed upgrade attempt and
  no helpful message.

  [Test Plan]

  Create a LXD container running Focal:

  $ lxc launch ubuntu:focal focal
  $ lxc shell focal bash

  Then, install postgresql, and upgrade to Jammy:

  $ apt install -y postgresql
  $ do-release-upgrade

  After upgrading to Jammy, attempt to upgrade to Noble:

  $ do-release-upgrade -d

  The upgrade will fail because the calculated upgrade requires removing
  postgresql-12. With the patch, a friendly message should be displayed
  explaining this.

  [Where problems could occur]

  This patch adds some extra logic when displaying a message after an
  upgrade aborts due to a problem with the calculated upgrade. Mistakes
  with this patch would probably affect the message displayed to the
  user in such cases.

  [Original Description]

  When running sudo do-release-upgrade -d
  I get follwing massage

  Checking package manager
  Reading package lists... Done

  Calculating the changes

  Calculating the changes

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade.

  This was likely caused by:
  * Unofficial software packages not provided by Ubuntu
  Please use the tool 'ppa-purge' from the ppa-purge
  package to remove software from a Launchpad PPA and
  try the upgrade again.

  If none of this applies, then please report this bug using the
  command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If
  you want to investigate this yourself the log files in
  '/var/log/dist-upgrade' will contain details about the upgrade.
  Specifically, look at 'main.log' and 'apt.log'.

  I think already tried removed the third party packages and it is still
  not working
