Title:
  aptitude removes packages conflicting with requested package even if
  it was not downloaded

Status in aptitude:
  Confirmed
Status in “aptitude” package in Ubuntu:
  Fix Committed

Bug description:
  Binary package hint: aptitude

  I had been testing connman and indicator-network but found that they
  did not yet support WPA-Enterprise. Therefore I thought I could
  install network-manager and network-manager-gnome. Forgetting that I
  was not online, I ran "sudo aptitude install network-manager-gnome",
  was asked if I wanted to solve the conflict by removing the
  conflicting packages (connman and indicator-network), answered yes and
  ended up with neither of the packages installed. This happened because
  aptitude proceeded with removing connman and indicator-network even
  though the packages to replace it were not fetched.

  1) $ lsb_release -rd
  Description:	Ubuntu Natty (development branch)
  Release:	11.04

  2) $ apt-cache policy aptitude
  aptitude:
    Installed: 0.6.3-3.2ubuntu1
    Candidate: 0.6.3-3.2ubuntu1
    Version table:
   *** 0.6.3-3.2ubuntu1 0
          500 http://archive.ubuntu.com/ubuntu/ natty/main amd64 Packages
          100 /var/lib/dpkg/status

  3) I expected the packages to be either downloaded or the whole
  transaction to be rolled back.

  4) The transaction continued, and the conflicting packages (in this
  case connman and indicator-network) were removed, although the
  packages which were to replace them (network-manager and network-
  manager-gnome) had not been downloaded. That way I was left without an
  internet connection (except that the cache still contained connman and
  indicator-network so I could install them again and fix the problem in
  another way).
