Bug#992065: mpich: libhdf5-mpich-dev upgrade problems if libmpich1.0-dev is still installed

[Andreas Beckmann]

Package: mpich
Version: 3.4.1-4
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts
Control: affects -1 + libhdf5-mpich-dev

During an piuparts upgrade test of libhdf5-mpich-dev on the upgrade path
  squeeze -> wheezy -> jessie -> stretch -> buster -> bullseye
I observed this failure:

  Setting up libhdf5-mpich-dev (1.10.6+repack-4) ...
  update-alternatives: priority must be an integer

  Use 'update-alternatives --help' for program usage information.
  dpkg: error processing package libhdf5-mpich-dev (--configure):
   installed libhdf5-mpich-dev package post-installation script subprocess returned error exit status 2


mpi alternative setting after the failure
(after upgrade squeeze...bullseye):

 mpifort /usr/bin/mpifort.mpich


OK, that is still an ancient mpi alternative at the time
libhdf5-mpich-dev.postinst runs ...

Probably caused by libmpich1.0-dev providing libmpich-dev and therefore
no newer libmpich-dev getting installed.

Trying to add some Breaks/Replaces ... tests running ...

BTW, installing libmpich-dev in the failure state causes

Selecting previously unselected package mpich.
Preparing to unpack .../31-mpich_3.4.1-4_amd64.deb ...
Unpacking mpich (3.4.1-4) ...
dpkg: error processing archive /tmp/apt-dpkg-install-S2t7dN/31-mpich_3.4.1-4_amd64.deb (--unpack):
 trying to overwrite '/usr/bin/mpicc.mpich', which is also in package libmpich1.0-dev 1.2.7-9.1
