Package: libcw-dev,libcw7 Version: 3.6.0-1 Severity: serious User: debian-qa@lists.debian.org Usertags: piuparts replaces-without-breaks Hi, during a test with piuparts and DOSE tools I noticed your package causes removal of files that also belong to another package. This is caused by using Replaces without corresponding Breaks. The installation sequence to reproduce this problem is apt-get install libcw6-dev # (1) apt-get install libcw-dev apt-get remove libcw-dev # (2) The list of installed files at points (1) and (2) should be identical, but the following files have disappeared: /usr/include/libcw.h /usr/include/libcw_debug.h /usr/lib/x86_64-linux-gnu/libcw.a /usr/lib/x86_64-linux-gnu/libcw.so /usr/lib/x86_64-linux-gnu/pkgconfig/libcw.pc /usr/share/man/man3/libcw.3.gz /usr/share/man/man7/cw.7.gz This is a serious bug violating policy 7.6, see https://www.debian.org/doc/debian-policy/ch-relationships.html#overwriting-files-and-replacing-packages-replaces and also see the footnote that describes this incorrect behavior: https://www.debian.org/doc/debian-policy/ch-relationships.html#id13 The libcw-dev package has the following relationships with libcw6-dev: Conflicts: n/a Replaces: libcw3-dev, libcw4-dev, libcw5-dev, libcw6-dev, unixcw-dev Breaks: libcw3-dev, unixcw-dev The libcw7 package has the following relationships with libcw6: Conflicts: n/a Replaces: libcw3, libcw4, libcw5, libcw6, unixcw Breaks: libcw3, unixcw >From the attached log (scroll to the bottom...): 0m25.1s ERROR: FAIL: After purging files have disappeared: /usr/include/libcw.h owned by: libcw-dev /usr/include/libcw_debug.h owned by: libcw-dev /usr/lib/x86_64-linux-gnu/libcw.a owned by: libcw-dev /usr/lib/x86_64-linux-gnu/libcw.so -> libcw.so.6.6.1 owned by: libcw-dev /usr/lib/x86_64-linux-gnu/pkgconfig/libcw.pc owned by: libcw-dev /usr/share/man/man3/libcw.3.gz owned by: libcw-dev /usr/share/man/man7/cw.7.gz owned by: libcw7:amd64 0m25.1s ERROR: FAIL: After purging files have been modified: /var/lib/dpkg/info/libcw6-dev.list not owned /var/lib/dpkg/info/libcw6:amd64.list not owned cheers, Andreas
