Hi, >If the deep investigation you wrote about consists in passing all the auto-tests on amd64 and i386 on both stretch/sid and jessie/stable, and make a diff, it will >take a lot of time to me (considering I do not have a stretch pbuilder environment ready :( ). stretch/sid are already fine. Jessie needs probably investigation if you want a stretch pbuilder... pbuilder-dist stretch amd64 create or pbuilder-dist stretch i386 create end. G.
