Answer 1

Para mim, foi bom instalar python-dev package antes.

    

Answer 2

Digite estes dois comandos:

sudo apt-get clean
sudo apt-get autoclean

Tente corrigir as dependências quebradas:

sudo apt-get -f install
sudo dpkg --configure -a

e insira novamente sudo apt-get -f install .

Isso deve resolver seus problemas de dependência e agora você pode instalar seu pacote.
