[Debichem-devel] Bug#973639: libgromacs6: missing Breaks+Replaces: libgromacs5

[Andreas Beckmann]

Package: libgromacs6
Version: 2021~beta1-1
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
'sid' to 'experimental'.
It installed fine in 'sid', then the upgrade to 'experimental' 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 .../libgromacs6_2021~beta1-1_amd64.deb ...
  Unpacking libgromacs6:amd64 (2021~beta1-1) ...
  dpkg: error processing archive /var/cache/apt/archives/libgromacs6_2021~beta1-1_amd64.deb (--unpack):
   trying to overwrite '/usr/lib/x86_64-linux-gnu/libgmxapi.so.0.1.0', which is also in package libgromacs5:amd64 2020.4-2
  dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)
  Errors were encountered while processing:
   /var/cache/apt/archives/libgromacs6_2021~beta1-1_amd64.deb
 
Shared libraries with independent soversions shouldn't be bundled in the same
binary package.


cheers,

Andreas
