Bug#798357: libnetcdf-cxx-legacy-dev: fails to upgrade from 'jessie' - trying to overwrite /usr/share/info/netcdf-cxx.info.gz

[Andreas Beckmann]

Package: libnetcdf-cxx-legacy-dev
Version: 4.2-1
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
'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...):

   trying to overwrite '/usr/share/info/netcdf-cxx.info.gz', which is also in package netcdf-doc 1:4.1.3-7.2
  Errors were encountered while processing:

cheers,
