[Pkg-giraffe-maintainers] Bug#857377: kopano-dev: fails to upgrade from 'jessie' - trying to overwrite /usr/lib/x86_64-linux-gnu/libmapi.so

[Andreas Beckmann]

Package: kopano-dev
Version: 8.1.0-3
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 'sid' 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...):

  Selecting previously unselected package kopano-dev.

   trying to overwrite '/usr/lib/x86_64-linux-gnu/libmapi.so', which is also in package libmapi-dev 1:2.2-5+b1
  Errors were encountered while processing:

cheers,

Andreas
