Package: ettercap-common,ettercap-graphical
Version: 1:0.8.1-1
Severity: serious
User: debian...@lists.debian.org
Usertags: piuparts replaces-without-breaks

Hi,

during a test with piuparts and DOSE tools I noticed your package causes
removal of files that also belong to another package.
This is caused by using Replaces without corresponding Breaks.

And of course by shipping the same file in two packages:

  usr/share/ettercap/ettercap.png

which looks like an incomplete move to another package.

The installation sequence to reproduce this problem is

  apt-get install ettercap-common
  # (1)
  apt-get install ettercap-graphical
  apt-get remove ettercap-graphical
  # (2)

The list of installed files at points (1) and (2) should be identical,
but the following files have disappeared:

  usr/share/ettercap/ettercap.png

This is a serious bug violating policy 7.6, see
http://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces
and also see the footnote that describes this incorrect behavior
http://www.debian.org/doc/debian-policy/footnotes.html#f53

The ettercap-graphical package has the following relationships with 
ettercap-common:

  Conflicts: N/A
  Breaks:    N/A
  Replaces:  ettercap, ettercap-common, ettercap-gtk, ettercap-text-only

I don't see what you want to achieve with these Replaces, so I cannot suggest 
a better solution. Please read the policy (and explain your intentions if you 
need help).
  Have packages been split? (version?)
  Have files moved between the packages? (version?)
  Should packages not be installable at the same time?
