Package: libiw30t64
Version: 30~pre9-16.1~exp1
Severity: serious
Tags: patch
User: helm...@debian.org
Usertags: dep17p1
Control: affects -1 + libiw30
X-Debbugs-Cc: vor...@debian.org
Installing libiw30t64 may cause file loss in an upgrade scenario.
Reproducer:
mmdebstrap --variant=apt --verbose bookworm /dev/null "deb
http://deb.debian.org/debian bookworm main" "deb http://deb.debian.org/debian
experimental main" --include=wireless-tools --chrooted-customize-hook="apt-get
download libiw30t64" --chrooted-customize-hook="echo libiw30 deinstall | dpkg
--set-selections" --chrooted-customize-hook="dpkg --auto-deconfigure --unpack
*.deb" --chrooted-customize-hook="dpkg --configure -a"
--chrooted-customize-hook="dpkg -r libiw30" --chrooted-customize-hook="! dpkg
--verify | grep ."
I'm attaching a patch for your convenience. I consider that libiw30 is
not as central as other packages and hence propose employing Conflicts
here. Conflicts allow removing the protective diversion in trixie's
postinst rather than forky's postinst already.
