Bug#722927: opencv-data: fails to upgrade from 'testing' - trying to overwrite /usr/share/opencv/haarcascades/haarcascade_frontalface_alt.xml

[Andreas Beckmann]

Package: opencv-data
Version: 2.4.6.1+dfsg-0exp2
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
http://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces

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

  Selecting previously unselected package opencv-data.
  Unpacking opencv-data (from .../opencv-data_2.4.6.1+dfsg-0exp2_all.deb) ...

  Errors were encountered while processing:

cheers,

Andreas

PS: you should switch back to regular versioning in sid ... -0exp2 is confusing :-)
