Problemas con apt-get

["Iñako" <inako@agoranet.es>]

Si hago "apt-get -u install heimdal-clients" me dice lo siguiente:

Sorry, but the following packages have unmet dependencies:
  heimdal-clients: Depends: libgssapi1-heimdal (>= 0.4e-7.woody.8) but
it is not going to be installed
                   Depends: libhdb7-heimdal (>= 0.4e-7.woody.8) but it
is not going to be installed
                   Depends: libkadm5clnt4-heimdal (>= 0.4e-7.woody.8)
but it is not going to be installed
                   Depends: libkadm5srv7-heimdal (>= 0.4e-7.woody.8) but
it is not going to be installed
                   Depends: libkafs0-heimdal (>= 0.4e-7.woody.8) but it
is not going to be installed
                   Depends: libkrb5-17-heimdal (>= 0.4e-7.woody.8) but
it is not going to be installed

¿Como puedo hacer para que me instale todas esas dependencias y las
depencias
que puedan tener las mismas?

Gracias de antemano
