[Ngassam Nkwenga]

I notice some day ago that update-manager dshows nomore any details on what it would be doing when running dist-upgrade:

I still get number of package to newly installed, removed, updated and kept back,
but I cannot see the name of the involved packages.( when clicking on Details )
