Dependência não satisfeita após a atualização da distribuição do mint do linux

Question

Atualizei recentemente para o Linux mint rebecca. Estou recebendo dependências não atendidas para apt-get

quando estou tentando apt-get install de um pacote chamado monodevelop-nunit monodoc-nunit-manual , isso acontece.

sudo apt-get install monodevelop-nunit monodoc-nunit-manual

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 mint-mdm-themes : Depends: mint-mdm-themes-html but it is not going to be installed
 monodevelop-nunit : Depends: libnunit-core-interfaces2.6.3-cil but it is not going to be installed
                     Depends: libnunit-core2.6.3-cil but it is not going to be installed
                     Depends: libnunit-framework2.6.3-cil but it is not going to be installed
                     Depends: libnunit-util2.6.3-cil but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

então eu faço isso

 apt-get -f install

minha source.list é assim

 cat /etc/apt/sources.list

  # deb-src http://apt.jenslody.de/ any main
#deb cdrom:[Linux Mint 16 _petra_ - Release i386 20131126]/ saucy contrib main non-free   deb http://apt.wxwidgets.org/ squeeze-wx main

como posso resolver isso?
