Bug#962831: libmumps-headers-dev: missing Breaks+Replaces: libmumps-seq-dev (<= 5.3.1-2)

[Andreas Beckmann]

Package: libmumps-headers-dev
Version: 5.3.1-3
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
'testing'.
It installed fine in 'testing', 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#overwriting-files-and-replacing-packages-replaces

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

  Preparing to unpack .../libmumps-headers-dev_5.3.1-3_all.deb ...
  Unpacking libmumps-headers-dev (5.3.1-3) ...
  dpkg: error processing archive /var/cache/apt/archives/libmumps-headers-dev_5.3.1-3_all.deb (--unpack):
   trying to overwrite '/usr/include/mumps_seq/elapse.h', which is also in package libmumps-seq-dev:amd64 5.3.1-2
  Errors were encountered while processing:
   /var/cache/apt/archives/libmumps-headers-dev_5.3.1-3_all.deb

cheers,

Andreas
