Package: dpkg Version: 1.16.2 Severity: normal I'm trying this multiarch stuff. The plan was to find a couple of packages that I don't normally use, with a small set of dependencies, and try to install the i386 version of those packages on amd64. The packages I chose were mboxgrep and pcregrep because I already installed libpcre3:i386 as a first test. Here's the result, notice how it wants to upgrade libbz2 which was still the non-multiarch version from squeeze:
