Hi, an upgrade test with piuparts revealed that your package installs files over existing symlinks and possibly overwrites files owned by other packages. This usually means an old version of the package shipped a symlink but that was later replaced by a real (and non-empty) directory. This kind of overwriting another package's files cannot be detected by dpkg. This was observed on the following upgrade paths: sid -> experimental For /usr/share/doc/PACKAGE this may not be problematic as long as both packages are installed, ship byte-for-byte identical files and are upgraded in lockstep. But once one of the involved packages gets removed, the other one will lose its documentation files, too, including the copyright file, which is a violation of Policy 12.5: https://www.debian.org/doc/debian-policy/ch-docs.html#copyright-information For other overwritten locations anything interesting may happen. Note that dpkg intentionally does not replace directories with symlinks and vice versa, you need the maintainer scripts to do this. See in particular the end of point 4 in https://www.debian.org/doc/debian-policy/ch-maintainerscripts.html#details-of-unpack-phase-of-installation-or-upgrade It is recommended to use the dpkg-maintscript-helper commands 'dir_to_symlink' and 'symlink_to_dir' (available since dpkg 1.17.14) to perform the conversion, ideally using d/$PACKAGE.maintscript. See dpkg-maintscript-helper(1) and dh_installdeb(1) for details. >From the attached log (scroll to the bottom...): 0m37.3s ERROR: FAIL: silently overwrites files via directory symlinks: /usr/share/doc/g++-mingw-w64-i686/changelog.Debian.gz (g++-mingw-w64-i686) != /usr/share/doc/gcc-mingw-w64-base/changelog.Debian.gz (gcc-mingw-w64-base) /usr/share/doc/g++-mingw-w64-i686 -> gcc-mingw-w64-base /usr/share/doc/g++-mingw-w64-i686/changelog.gz (g++-mingw-w64-i686) != /usr/share/doc/gcc-mingw-w64-base/changelog.gz (gcc-mingw-w64-base) /usr/share/doc/g++-mingw-w64-i686 -> gcc-mingw-w64-base /usr/share/doc/g++-mingw-w64-i686/copyright (g++-mingw-w64-i686) != /usr/share/doc/gcc-mingw-w64-base/copyright (gcc-mingw-w64-base) /usr/share/doc/g++-mingw-w64-i686 -> gcc-mingw-w64-base /usr/share/doc/gcc-mingw-w64-i686/changelog.Debian.gz (gcc-mingw-w64-i686) != /usr/share/doc/gcc-mingw-w64-base/changelog.Debian.gz (gcc-mingw-w64-base) /usr/share/doc/gcc-mingw-w64-i686 -> gcc-mingw-w64-base /usr/share/doc/gcc-mingw-w64-i686/changelog.gz (gcc-mingw-w64-i686) != /usr/share/doc/gcc-mingw-w64-base/changelog.gz (gcc-mingw-w64-base) /usr/share/doc/gcc-mingw-w64-i686 -> gcc-mingw-w64-base /usr/share/doc/gcc-mingw-w64-i686/copyright (gcc-mingw-w64-i686) != /usr/share/doc/gcc-mingw-w64-base/copyright (gcc-mingw-w64-base) /usr/share/doc/gcc-mingw-w64-i686 -> gcc-mingw-w64-base 0m36.2s ERROR: FAIL: silently overwrites files via directory symlinks: /usr/share/doc/gcc-mingw-w64-x86-64/changelog.Debian.gz (gcc-mingw-w64-x86-64) != /usr/share/doc/gcc-mingw-w64-base/changelog.Debian.gz (gcc-mingw-w64-base) /usr/share/doc/gcc-mingw-w64-x86-64 -> gcc-mingw-w64-base /usr/share/doc/gcc-mingw-w64-x86-64/changelog.gz (gcc-mingw-w64-x86-64) != /usr/share/doc/gcc-mingw-w64-base/changelog.gz (gcc-mingw-w64-base) /usr/share/doc/gcc-mingw-w64-x86-64 -> gcc-mingw-w64-base /usr/share/doc/gcc-mingw-w64-x86-64/copyright (gcc-mingw-w64-x86-64) != /usr/share/doc/gcc-mingw-w64-base/copyright (gcc-mingw-w64-base) /usr/share/doc/gcc-mingw-w64-x86-64 -> gcc-mingw-w64-base /usr/share/doc/gfortran-mingw-w64-x86-64/changelog.Debian.gz (gfortran-mingw-w64-x86-64) != /usr/share/doc/gcc-mingw-w64-base/changelog.Debian.gz (gcc-mingw-w64-base) /usr/share/doc/gfortran-mingw-w64-x86-64 -> gcc-mingw-w64-base /usr/share/doc/gfortran-mingw-w64-x86-64/changelog.gz (gfortran-mingw-w64-x86-64) != /usr/share/doc/gcc-mingw-w64-base/changelog.gz (gcc-mingw-w64-base) /usr/share/doc/gfortran-mingw-w64-x86-64 -> gcc-mingw-w64-base /usr/share/doc/gfortran-mingw-w64-x86-64/copyright (gfortran-mingw-w64-x86-64) != /usr/share/doc/gcc-mingw-w64-base/copyright (gcc-mingw-w64-base) /usr/share/doc/gfortran-mingw-w64-x86-64 -> gcc-mingw-w64-base This seems to affect the full language x arch matrix. Note that dpkg-maintscript-helper symlink_to_dir etc. don't work reliably if the architecture changes between any and all. cheers, Andreas
