problemas com dependencias no apt-get

[Helder Pereira Cristo <helderpc@uaivip.com.br>]

Quando tendo usar o apt-get upgrade para atualizar o sistema recebo a
seguinte mensagem:

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
  dhcp3-server: Depends: dhcp3-common (= 3.0.1-1) but 3.0.1-2 is
installed
E: Unmet dependencies. Try using -f.

Se eu tento apt-get -f install e confirmo que quero instalar o
dhcp3-server recebo:

Preconfiguring packages ...

Preparing to replace dhcp3-server 3.0.1-1

Errors were encountered while processing:
 /var/cache/apt/archives/dhcp3-server_3.0.1-2_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Não consigo retirar nem reinstalar esse pacote que está travando tudo.
Como posso recuperar esse script /etc/init.d/dhcp3-server? O que mais
posso fazer?
Obrigado,
Helder
