Sure. Just a few points/notes: - is (<<1:2.007) correct? I see 1:2.007-2.1+b1 was the first one on i386 that got built against perl 5.20, so technically the jessie perl breaks all the earlier ones, right? Also, AIUI the actual source change that fixes the breakage going forward is in 1:2.007-4 so it seems using that would be the most robust (think downstream distributions that might be upgrading their perl versions in a different schedule.) So is (<< 1:2.007-4) OK with you? - which perl packages need this? The minimal recipe I could come up for this is # wheezy base chroot apt-get install libpdl-stats-perl dpkg --unpack perl-modules_5.20.1-3_all.deb # from jessie dpkg --remove libpdl-stats-perl or, alternatively, # wheezy base chroot apt-get install libpdl-stats-perl dpkg -i libc6_2.19-13_amd64.deb dpkg --unpack perl-base_5.20.1-3_amd64.deb dpkg --remove libpdl-stats-perl Interestingly, unpacking the new 'perl' package alone doesn't trigger the failure. So it looks like we need the Breaks in both perl-base and perl-modules. - is Breaks sufficient, or do we need Conflicts? Dependency guarantees around 'postinst triggered' are not quite clear to me. I assume 'postinst triggered' will not be called before the package is configured, in which case I expect Breaks should be enough (as it will guarantee that the old pdl package gets deconfigured, and the new pdl package won't be configured before its dependencies are installed.) Will test this, but any advice is appreciated. I hope to be able to upload a fix this weekend, assuming the version number thing above is confirmed one way or another. -- Niko Tyni nt...@debian.org -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
