Bug#843354: libbrial{, -groebner}-dev: fails to upgrade from 'jessie' - trying to overwrite /usr/include/polybori/BlockDegLexOrder.h, ...

[Andreas Beckmann]

Package: libbrial-dev,libbrial-groebner-dev
Version: 0.8.5-2
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
