[PKG-Openstack-devel] Bug#891681: python3-nova: fails to upgrade from 'testing' - trying to overwrite /usr/share/apport/package-hooks/source_nova.py

[Andreas Beckmann]

Package: python3-nova
Version: 2:17.0.0~rc1-2
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/#overwriting-files-and-replacing-packages-replaces

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

  Selecting previously unselected package python3-nova.

   trying to overwrite '/usr/share/apport/package-hooks/source_nova.py', which is also in package python-nova 2:16.0.3-10
  Errors were encountered while processing:

cheers,

Andreas
