Bug#1133230: python3-cctbx has an undeclared file conflict on /usr/lib/python3/dist-packages/boost/__init__.py

[Helmut Grohne]

Package: python3-cctbx
Version: 2026.2+ds2+~3.27.0+ds1-1
Severity: serious
User: debian-qa at lists.debian.org
Usertags: fileconflict
Control: affects -1 + libboost-mpi-python1.83.0 libboost-mpi-python1.88.0

python3-cctbx has an undeclared file conflict. This may result in an
unpack error from dpkg.

The file /usr/lib/python3/dist-packages/boost/__init__.py is contained
in the packages
 * libboost-mpi-python1.83.0
   * 1.83.0-4.2 as present in trixie
   * 1.83.0-5+b2 as present in forky|unstable
 * libboost-mpi-python1.88.0
   * 1.88.0-1 as present in trixie
   * 1.88.0-1.4+b2 as present in forky|unstable
 * python3-cctbx/2026.2+ds2+~3.27.0+ds1-1 as present in unstable

These packages can be unpacked concurrently, because there is no
relevant Replaces or Conflicts relation. Attempting to unpack these
packages concurrently results in an unpack error from dpkg, because none
of the packages installs a diversion for the affected file.

Kind regards
