[Debian-med-packaging] Bug#959850: t-coffee-examples: missing Breaks+Replaces: t-coffee (<< 13)

[Andreas Beckmann]

Package: t-coffee-examples
Version: 13.41.0.28bdc39+dfsg-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...):
