[Pkg-vala-maintainers] Bug#661400: libvala-0.12-dev: removal of libvala-0.12-dev makes files disappear from libvala-0.10-dev

Package: libvala-0.12-dev
Version: 0.12.1-2
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts replaces-without-breaks


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

The installation sequence to reproduce this problem is

  apt-get install libvala-0.10-dev
  # (1)
  apt-get install libvala-0.12-dev
  apt-get remove libvala-0.12-dev
  # (2)

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


This is a serious bug violating policy 7.6, see
and also see the footnote that describes this incorrect behavior

The libvala-0.12-dev package has the following relationships with libvala-0.10-dev:

  Conflicts: n/a
  Breaks:    n/a
  Replaces:  libvala-0.10-dev
