Bug#984474: libbio-asn1-entrezgene-perl: missing Breaks+Replaces: libbio-perl-perl (<< 1.7.3)

[Andreas Beckmann]

Package: libbio-asn1-entrezgene-perl
Version: 1.730-1
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
'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-asn1-entrezgene-perl.
  Preparing to unpack .../039-libbio-asn1-entrezgene-perl_1.730-1_all.deb ...
  Unpacking libbio-asn1-entrezgene-perl (1.730-1) ...
  dpkg: error processing archive /tmp/apt-dpkg-install-eyjeT8/039-libbio-asn1-entrezgene-perl_1.730-1_all.deb (--unpack):
   trying to overwrite '/usr/share/man/man3/Bio::SeqIO::entrezgene.3pm.gz', which is also in package libbio-perl-perl 1.7.2-3

IIRC bioperl 1.7.3 is the version that got split up into several packages,
thus the existing B+R: libbio-perl-perl (<= 1.7.2) is insufficient.


cheers,

Andreas
