Bug#1027402: overwrites file from libsundials-nvecparallel-mpi4 without declaring proper relationship

[Sébastien Villemot]

Package: libsundials-nvecparallel-mpi6
Version: 6.4.1+dfsg1-2
Severity: serious

Dear Maintainer,

When upgrading, I got the following dpkg error:

Preparing to unpack .../libsundials-nvecparallel-mpi6_6.4.1+dfsg1-2+b1_amd64.deb ...
Unpacking libsundials-nvecparallel-mpi6:amd64 (6.4.1+dfsg1-2+b1) ...
dpkg: error processing archive /var/cache/apt/archives/libsundials-nvecparallel-mpi6_6.4.1+dfsg1-2+b1_amd64.deb (--unpack):
 trying to overwrite '/usr/lib/x86_64-linux-gnu/libsundials_fnvecmpimanyvector_mod.so.6.4.1', which is also in package libsundials-nvecparallel-mpi4:amd64 6.4.1+dfsg1-1
Errors were encountered while processing:
 /var/cache/apt/archives/libsundials-nvecparallel-mpi6_6.4.1+dfsg1-2+b1_amd64.deb

I guess a Breaks+Replaces relationship is missing.

Thanks for your work,
