[Python-modules-team] Bug#813399: python-pip-whl: fails to upgrade from 'testing' - trying to overwrite /usr/share/python-wheels/six-1.10.0-py2.py3-none-any.whl

[Andreas Beckmann]

Package: python-pip-whl
Version: 8.0.2-2
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
'testing'.
It installed fine in 'testing', 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#s-replaces

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

  Selecting previously unselected package python-pip-whl.
  Preparing to unpack .../python-pip-whl_8.0.2-2_all.deb ...

  dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

cheers,

Andreas
