apt has no way to accomodate having two distinct packages in the cache with the same version number, and I don't see any reason why it should. (package,version) should refer unambiguously to a package, and that assumption is deep in the packaging toolchain. > What makes it think the one installed is not the available one ?

This sort of thing happens, for example, if the metadata in the Packages file doesn't match the package that is actually available. apt has no way to d -- - mdz
