Erros foram encontrados durante o processamento: python-minimal

Question

Eu não posso fazer nada com o apt-get por causa do python-minimal . Acho que posso ter corrompido meu python!

Sempre que eu quiser instalar, remover ou atualizar usando apt-get , isso me dá este erro:

Errors were encountered while processing:
    python-minimal

Eu tentei pesquisar e tentei todas as soluções que encontrei sobre esse problema. Agora, estou em um ponto em que quero desinstalar e instalar de forma limpa uma nova versão do python.

Estas são as coisas que eu tentei até agora:

Primeiro, eu tinha o python instalado, e todo comando apt-get resultou nesse saída:

todos esses comandos:

sudo apt-get autoremove -f
sudo apt-get autoclean # and then install python
sudo apt-get upgrade
sudo apt-get -f install
sudo apt-get download python-minimal; sudo dpkg -i py*deb
sudo apt-get remove python
sudo apt-get autoremove python-minimal
sudo apt-get install --reinstall python-minimal

resultou nesta mesma saída:

 python-minimal
E: Sub-process /usr/bin/dpkg returned an error code (1)

então eu tentei isso , this , isto , isto e isto e nada funcionou para mim.

então eu me cansei e tentei remover manualmente o python, então eu removi arquivos python com rm -rf e agora este comando:

sudo apt-get upgrade python -f

resulta em:

e agora, quando eu executo sudo apt-get purge python-minimal , obtenho

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 python : Depends: python-minimal (= 2.7.5-5ubuntu3) but it is not 
going to be installed
 python-support : Depends: python-minimal but it is not going to be 
installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or 
specify a solution).

e depois de executar sudo apt-get -f install , obtenho

executando este comando sudo dpkg --configure -a me dá a seguinte saída:
