I could always change these to arch:any if it simplifies migration. My suggested strategy: Produce and test the necessary fixes on dhcpcd 10 first, then backport cherry-picks to dhcpcd 9 for bookworm-proposed-updates. Martin-Éric

I vaguely recall something in Scott's old maintainer files adding/removing a symbolic link.

Indeed. Martin-Éric

Ack. Currently in NEW. That probably won't work and will cause a reject, since it drops the epoch from a source package that previously (up to wheezy) had an epoch. I've tested adding the epoch to the bookworm package in my piuparts framework, and that seems to make the upgrades succeed if the package version from wheezy is still installed. Please also add this dhcpcd.preinst script to clean up leftovers from the wheezy package. = >8 = #!/bin/sh set -e if dpkg --compare-versions "$2" lt-nl "1:10.0.1-2~" ; then # cleanup leftovers from dhcpcd 1:3.* in wheezy # can be removed after the release of trixie update-alternatives --remove dhcpcd /sbin/dhcpcd3 if [ -d /etc/dhcpc ]; then test ! -h /etc/dhcpc/resolv.conf || rm -fv /etc/dhcpc/resolv.conf rmdir --ignore-fail-on-non-empty /etc/dhcpc fi fi #DEBHELPER# = 8< = (the version "1:10.0.1-2~" assumes the preinst gets added in the 1:10.0.1-2 upload) Btw, if you think that this or anything else is worthy of a cherry-pick for bookworm-updates, suggestions are welcome. The re-addition of the epoch definitively needs to backported to bookworm-pu, otherwise the upcoming usrmerge upload (with additional Breaks) to bookworm-pu will make dhcpcd uninstallable. The preinst is needed as well (but with a version of "1:9.4.1-22+deb12u1~" in the test) as the leftover alternative seems to be the source of the usrmerge conflict noticed in wicd-daemon. (The bookworm-pu upload needs to use the old source package name dhcpcd5 (and version 9.4.1-22+deb12u1), but you can update the Vcs-* URLs if you want to put the bookworm branch in the "new" repository location.)

Please do that. While doing more piuparts tests starting from ancient releases, I found that the combination of dhcpcd/wheezy with dhcpcd5/bullseye prevents the installation of usrmerge (and thus the upgrade to bookworm) with FATAL ERROR: Both /sbin/dhcpcd and /usr/sbin/dhcpcd exist. This package combination is e.g. achieved by installing wicd-daemon in wheezy and upgrading release by release to bookworm. To solve that, we need to add Conflicts: dhcpcd (<< 1:5~) to usrmerge which will make dhcpcd in sid (and bookworm) uninstallable due to the missing epoch. Andreas

IIRC you need to add the epoch > manually in the former case. Merely re-introducing the epoch for bin:dhcpcd ought to be enough. dhcpcd5 depends on a versionless dhcpcd. Thus: override_dh_gencontrol: dh_gencontrol --package=dhcpcd -- -v1:$(DEB_VERSION_UPSTREAM_REVISION) dh_gencontrol --remaining-packages Would probably be enough to make this policy-compliant again.

I'm not sure whether the transitional dhcpcd5 package should have a versioned dependency on the "right" dhcpcd, either (= 1:${binary:Version}) or (>= 1:9). IIRC you need to add the epoch manually in the former case. Andreas
