The question is how to get pdl to be updated earlier, I guess. or in a more general sense provide "do not care about failure" during dist-upgrade info to apt-get > If I could reproduce the problem, I'd probably try Andreas' > suggestion to add a versioned Breaks against older pdl versions to > altree. although it may sound more invasive, I think that also altree is not to 'blame' for this problem... so the breaks should go to the perl packages... -- c u henning -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
