Estou tentando instalar pacotes diferentes, mas mostrando dependências não atendidas na maioria deles, mesmo depois de sudo apt-get -f install .
Abaixo está o meu arquivo /etc/apt/sources.list :

Você misturou wheezy e squeeze no seu sources.list . Eles podem ser usados juntos, mas você deve configurar corretamente a fixação.
O mais provável é que você deva apenas alterar o squeeze (oldstable) para wheezy (estável no momento) e atualizar o sistema inteiro para estável, a documentação sobre atualização pode ser encontrada aqui
