Title:
  Kubuntu minimal install is converted to full install when upgraded to
  18.10

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

Bug description:
  1) 'lsb_release -rd'
  Description:    Ubuntu 18.04.1 LTS
  Release:        18.04

  2) 'apt-cache policy ubuntu-release-upgrader-core'
  ubuntu-release-upgrader-core:
    Installed: 1:18.04.28
    Candidate: 1:18.04.28

  3) What you expected to happen
  A user who chooses the "minimal install" option introduced in Bionic Beaver expects that an upgrade to Cosmic will retain the minimal package set.

  4) What happened instead
  The release upgrade for Kubuntu 18.04 to Kubuntu 18.10 installs applications not included in a minimal install.

  5) Background
  After reading the experience of two users in 
  https://www.kubuntuforums.net/showthread.php/74565-How-do-I-update-while-maintaining-a-minimal-desktop, I checked this myself as follows:

  I downloaded the Kubuntu 18.04.1 iso
  installed it using the minimal option in a VM
  ran sudo apt update and sudo apt full-upgrade
  rebooted
  changed software sources to notify of normal releases
  ran sudo do-release-upgrade 

  When I chose to view details at the "Continue [yN]  Details [d]d" prompt, there were the following lists of packages:
  "No longer supported:"
  "Remove:"
  "Install:"
  and
  "Upgrade:"

  Of the four, the "Install:" list contained packages such as 
  akregator
  cantata
  kmahjongg 
  kmail 
  kmines
  knotes 
  kontact 
  konversation
  ksudoku
  libreoffice-base 
  libreoffice-calc 
  libreoffice-draw 
  libreoffice-impress
  libreoffice-math
  libreoffice-writer
  just to list a few well-known packages.

  In effect, the upgrade of a minimal install option of Kubuntu 18.04 to
  Kubuntu 18.10 converts the system to a full install of Kubuntu 18.10.
  The same procedure works as expected for Ubuntu and Ubuntu Mate which
  both retain the "minimal state".
