[Debian-med-packaging] Bug#984475: libbio-db-ncbihelper-perl: missing Breaks+Replaces: bioperl (<< 1.7.3)

[Andreas Beckmann]

Package: libbio-db-ncbihelper-perl
Version: 1.7.6-2
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts
Control: affects -1 + bioperl-run

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'buster'.
It installed fine in 'buster', then the upgrade to 'bullseye' 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...):

  Selecting previously unselected package libbio-db-ncbihelper-perl.
  Preparing to unpack .../045-libbio-db-ncbihelper-perl_1.7.6-2_all.deb ...
  Unpacking libbio-db-ncbihelper-perl (1.7.6-2) ...
  dpkg: error processing archive /tmp/apt-dpkg-install-eyjeT8/045-libbio-db-ncbihelper-perl_1.7.6-2_all.deb (--unpack):
   trying to overwrite '/usr/bin/bp_biofetch_genbank_proxy', which is also in package bioperl 1.7.2-3

IIRC bioperl 1.7.3 is the version that got split up into several packages.


cheers,

Andreas
