Package: wireless-tools Version: 30~pre9-22 Severity: serious Justification: fails to upgrade from testing
libiw30t64 fails to install when libiw30 is present, because the Conflicts field hardcodes a version bound that the installed libiw30 (e.g. 30~pre9-16+b1) does not satisfy: Conflicts: libiw30 (<< 30~pre9) dpkg --compare-versions "30~pre9-16+b1" ge "30~pre9" is true, so the conflict never triggers and libiw30t64 tries to overwrite a file still owned by libiw30: dpkg: error processing archive .../libiw30t64_30~pre9-22_amd64.deb (--unpack): trying to overwrite '/usr/lib/x86_64-linux-gnu/libiw.so.30', which is also in package libiw30:amd64 (30~pre9-16+b1) Fix: use unconditional Conflicts/Replaces, since libiw30t64 and libiw30 can never coexist regardless of version: Conflicts: libiw30 Replaces: libiw30 Reported by a user via email after upgrading from testing. -- Ahmed Alaoui
