Eu não pude ver o centro de software no meu Ubuntu, então me referi a essa resposta e vi pacotes quebrados, então tentei sudo apt-get install -f , mas ele disse 0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded. . Quando tentei instalar o software center com o comando abaixo, o erro aparece.
