Package: dpkg Version: 1.17.6 Severity: normal User: helm...@debian.org Usertags: rebootstrap
Dear maintainer, Please imagine the following obscure scenario. (Yes, I actually managed to reproduce it in a real world example.) Package b:amd64 depends on a:amd64 M-A:same. Both are installed, all is fine. Now for some reason we obtain a:i386 of the same version as a but being M-A:none. This is a bug in package a of course. However, dpkg does not fail loudly enough in my opinion. It just replaces a:amd64 with a:i386 and pretends that everything is fine. Worse, dpkg --audit will not complain. Please find a script for reproducing the issue (in e.g. pbuilder) and a log attached. Helmut
