Bug#984528: libcod-tools-perl: missing Breaks+Replaces: cod-tools (<< 3)

[Andreas Beckmann]

Package: libcod-tools-perl
Version: 3.1.0+dfsg-1
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts
Control: affects -1 + cod-tools

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...):
