Severity: serious
User: debian-qa@lists.debian.org
Usertags: fileconflict

libogdf-tulip-6.0, libtulip-python-6.0 and tulip have an undeclared file
conflict.  This may result in an unpack error from dpkg.

The file /usr/lib/${DEB_HOST_MULTIARCH}/tulip/libOGDFPlugins-6.0.1.so is
contained in the packages
 * libogdf-tulip-6.0
   * 6.0.1+dfsg-2+b1 as present in unstable
   * 6.0.1+dfsg-2 as present in forky
 * tulip
   * 6.0.1+dfsg-2 as present in forky
   * 6.0.1+dfsg-2+b1 as present in unstable

The file /usr/lib/${DEB_HOST_MULTIARCH}/tulip/libtulip-python-6.0.1.so is
contained in the packages
 * libtulip-python-6.0
   * 6.0.1+dfsg-2+b1 as present in unstable
   * 6.0.1+dfsg-2 as present in forky
 * tulip
   * 6.0.1+dfsg-2 as present in forky
   * 6.0.1+dfsg-2+b1 as present in unstable

These packages can be unpacked concurrently, because there is no
relevant Replaces or Conflicts relation.  Attempting to unpack these
packages concurrently results in an unpack error from dpkg, because none
of the packages installs a diversion for the affected files.

Kind regards
