Hi. I figure out the issue.
There was a previous installation of "libpango1.0-0:i386" in rc state that prevent "libpango1.0-0:amd64" to be removed and lock the installation for new version of "libpango1.0-0:all" After "dpkg -P libpango1.0-0:i386" I'm now able to upgrade the package. I think it's dpkg's issue as decribed in #682365 [1] [1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=682365 Regards. Matteo.
