[Debian-med-packaging] Bug#1021543: unifrac-tools: missing Breaks+Replaces: libssu-tools (<< 1)

[Andreas Beckmann]

Package: unifrac-tools
Version: 1.1.1-1
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
'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 .../unifrac-tools_1.1.1-3_amd64.deb ...
  Unpacking unifrac-tools (1.1.1-3) ...

  Errors were encountered while processing:

The following files are conflicting:
  
  /usr/bin/faithpd
  /usr/bin/ssu
  /usr/share/man/man1/faithpd.1.gz
  /usr/share/man/man1/ssu.1.gz


cheers,
