thanks for reply, but the problem is 2) Have a version number less than the version in the Packages file.
look at these packages: main/m/mutter/gir1.2-mutter-3.0_3.12.2-2_i386.deb main/m/mutter/gir1.2-mutter-3.0_3.12.2-2+b1_i386.deb the sort gives gir1.2-mutter-3.0_3.12.2-2_i386.deb more recent, but in fact gir1.2-mutter-3.0_3.12.2-2+b1_i386.deb is more recent regards
