[Debian-med-packaging] Bug#854329: ncbi-tools-bin: fails to upgrade from 'jessie' - trying to overwrite /usr/bin/taxblast

[Andreas Beckmann]

Package: ncbi-tools-bin
Version: 6.1.20170106-1
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
'jessie'.
It installed fine in 'jessie', then the upgrade to 'stretch' 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#s-replaces

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

  Preparing to unpack .../ncbi-tools-bin_6.1.20170106-1_i386.deb ...
  Unpacking ncbi-tools-bin (6.1.20170106-1) over (6.1.20120620-8) ...

cheers,

Andreas
