[pkg-go] Bug#973629: golang-gopkg-alecthomas-kingpin.v3-dev: missing Breaks+Replaces: golang-gopkg-alecthomas-kingpin.v2-dev

[Andreas Beckmann]

Package: golang-gopkg-alecthomas-kingpin.v3-dev
Version: 3.0~git20180227.b8d601d-1
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package failed to install
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...):
