L'équivalent de rpm -qV, bien mieux que debsums qui se limite à verifier quelques fichiers. J'ai l'impression que dpkg -V vérifie bien TOUS les fichiers du packages (même ceux dans /etc)

-V, --verify [package-name...]
Verifies the integrity of package-name or all packages if omit‐
ted, by comparing information from the installed paths with the
database metadata.

      The output format is selectable with the --verify-format option,
      which by default uses the rpm format, but that might  change  in
      the  future,  and  as  such programs parsing this command output
      should be explicit about the format they expect.
