I know, the fact that it's the case though, allow us to plan for a smoother transition.

That' be great (if not already done) to open important bugs on those packages please, so that we can track that down. I just opened a meta-bug to track the libjpeg transition on release.debian.org, please mark those bugs as blocking the meta-bug, it'll help us track them TIA. > I can provide you the logs if you want. I believe you, and only 6 ftbfs is relatively good news. The problem is, packages have to migrate together. The more packages that makes, the more probable it is the transition gets mixed up with another one. So I ask again, please let's do the -dev switch _first_ then bug packages wrongly depending upon libjpeg62-dev. The later can be done incrementally without, the first bit cannot. In the end we _do_ want all packages Build-Depending upon libjpeg-dev, that's clear. Though the smoother path is making them switch after the transition is done, not before. -- ·O· Pierre Habouzit ··O madco...@debian.org OOO http://www.madism.org
