[Debichem-devel] Bug#718001: gromacs-mpich, gromacs-openmpi: fails to upgrade from wheezy - trying to overwrite /usr/lib/libgmxpreprocess_mpi_d.mpich.so

[Andreas Beckmann]

Package: gromacs-mpich,gromacs-openmpi
Version: 4.6.3-1
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'wheezy'.
It installed fine in 'wheezy', then the upgrade to 'jessie' fails
because it tries to overwrite other packages files without declaring a
Breaks+Replaces relation.

See policy 7.6 at
http://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces
