Bug#903450: python3-veusz: fails to upgrade from 'testing' - trying to overwrite /usr/share/veusz/VERSION

[Andreas Beckmann]

Package: python3-veusz
Version: 3.0-1
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
'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...):

  Preparing to unpack .../python3-veusz_3.0-1_all.deb ...
  Unpacking python3-veusz (3.0-1) ...
  dpkg: error processing archive /var/cache/apt/archives/python3-veusz_3.0-1_all.deb (--unpack):
   trying to overwrite '/usr/share/veusz/VERSION', which is also in package veusz 1.21.1-1.3
  dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)
  Errors were encountered while processing:
   /var/cache/apt/archives/python3-veusz_3.0-1_all.deb


cheers,

Andreas
