Subject: libg2c-dev and libowfat-dev have an undeclared file conflict on
 /usr/share/man/man3/msg.3.gz
Message-ID: <20260410151917.GA755147@subdivi.de>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Delivered-To: submit@bugs.debian.org

Package: libg2c-dev,libowfat-dev
Severity: serious
User: debian-qa@lists.debian.org
Usertags: fileconflict

The file /usr/share/man/man3/msg.3.gz is contained in the packages
 * libg2c-dev/2.3.0-5 as present in forky|unstable
 * libowfat-dev/0.34-2 as present in forky|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 file.

Please figure out which of these packages should properly own the
affected file and reassign the bug as appropriate. When doing so, please
add the other package to the set of affected packages using "Control:
affects -1 + <packagename>" to avoid the filing of duplicates.

The other package should stop installing the file. In case the file is
being moved between packages, Breaks and Replaces should be declared. In
this case, please refer to policy section 7.6 for details. Another
useful resource is https://wiki.debian.org/PackageTransition.

Kind regards

Helmut Grohne
