Bug#816563: libjava-gmsh2: fails to upgrade from 'jessie' - trying to overwrite /usr/lib/i386-linux-gnu/libjava-gmsh.so

[Andreas Beckmann]

Package: libjava-gmsh2
Version: 2.11.0+dfsg1-2
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
'jessie'.
It installed fine in 'jessie', then the upgrade to 'stretch' fails
because it tries to overwrite other packages files without declaring a
Breaks+Replaces relation.

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

>From the attached log (scroll to the bottom...):

  Preparing to unpack .../libjava-gmsh2_2.11.0+dfsg1-2_i386.deb ...
  Unpacking libjava-gmsh2 (2.11.0+dfsg1-2) over (2.8.5+dfsg-1.1+b1) ...
