[Python-apps-team] Bug#919113: buildbot-doc: missing Breaks+Replaces: buildbot (<< 1.7.0)

[Andreas Beckmann]

Package: buildbot-doc
Version: 1.7.0-2
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
'stable'.
It installed fine in 'stable', then the upgrade to 'sid' 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

This test intentionally skipped 'testing' to find file overwrite
problems before packages migrate from 'unstable' to 'testing'.

>From the attached log (scroll to the bottom...):

  Preparing to unpack .../buildbot-doc_1.7.0-2_all.deb ...
  Unpacking buildbot-doc (1.7.0-2) ...
  dpkg: error processing archive /var/cache/apt/archives/buildbot-doc_1.7.0-2_all.deb (--unpack):
   trying to overwrite '/usr/share/doc/buildbot/html/_images/force-build.png', which is also in package buildbot 0.8.12-3.2
  dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
  Errors were encountered while processing:

cheers,

Andreas
