[Calendarserver-maintainers] Bug#563780: fails to install, trying to overwrite other packages files

[Holger Levsen]

Package: python-twisted-calendarserver
Version: 0.2.0.svn19773-5+b1
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts piuparts.d.o

Hi, 

during a test with piuparts I noticed your package failed to install because 
it tries to overwrite other packages files without declaring a 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 deselected package python-twisted-calendarserver.
  Unpacking python-twisted-calendarserver 
(from .../python-twisted-calendarserver
_0.2.0.svn19773-5+b1_amd64.deb) ...
  dpkg: error 
processing /var/cache/apt/archives/python-twisted-calendarserver_0.
2.0.svn19773-5+b1_amd64.deb (--unpack):
   trying to overwrite '/usr/share/pyshared/twisted/enterprise/adbapi.py', 
which 
is also in package python-twisted-core 0:9.0.0-0
  dpkg-deb: subprocess paste killed by signal (Broken pipe)
  Errors were encountered while processing:
   /var/cache/apt/archives/python-twisted-calendarserver_0.2.0.svn19773-5+b1_amd6
4.deb
  E: Sub-process /usr/bin/dpkg returned an error code (1)


regards,
	Holger
