Subject: libgtsam-dev fails to coinstall
Message-ID: <20260414162516.GA84206@subdivi.de>
MIME-Version: 1.0

Package: libgtsam-dev
Version: 4.2.0+dfsg-1+b4
Severity: serious
Justification: violates Debian policy 5.6.34.3
User: debian-qa@lists.debian.org
Usertags: fileconflict

libgtsam-dev is declared Multi-Arch: same, but fails to coinstall.

The files
 * /usr/lib/cmake/GTSAM/GTSAM-exports-relwithdebinfo.cmake
 * /usr/lib/cmake/GTSAM/GTSAM-exports.cmake
are shared by libgtsam-dev version 4.2.0+dfsg-1+b4 as present in trixie
and version 4.2.0+dfsg-6 as present in forky|unstable with varying
content.

Please ensure that shared files have bit-identical content across
architectures, move architecture-dependent files to
architecture-dependent paths or remove the Multi-Arch: same field.

Kind regards

Helmut Grohne
