apt-get Falha para todos os pacotes

Question

Sou um pouco novo no Linux (rodando o Ubuntu 14.04 - usando cerca de um ano), e recentemente comecei a ter problemas com o apt-get. Não consigo instalar ou remover nenhum pacote (erro abaixo). Eu tentei reinstalar esses pacotes, tentei excluir os arquivos deb e ainda recebo o mesmo erro.

    The following extra packages will be installed:
    python3-software-properties software-properties-common
    software-properties-gtk
    The following packages will be upgraded:
    python3-software-properties software-properties-common
    software-properties-gtk
    3 upgraded, 0 newly installed, 0 to remove and 412 not upgraded.
    108 not fully installed or removed.

    After this operation, 0 B of additional disk space will be used.

Answer 1

py3compile: not found

O comando py3compile faz parte do pacote python3-minimal , que parece estar corrompido.

Para corrigir o problema, tente o seguinte:

• Corrija um sistema com dependências quebradas no lugar:

  sudo apt-get  -f install
  

• Reconfigure todos os pacotes descompactados, mas não configurados, por:

  sudo dpkg --configure -a
  

• Se acima não ajudar, tente reinstalar python3-minimal package por:

  sudo apt install -f --reinstall python3-minimal
  

  Alternativamente, execute:

  apt-get download python3-minimal
  sudo dpkg -i *python3*.deb
  sudo apt install -f
  

  Ou faça o download do .pkg arquivo do kernel.org e instale a partir do o arquivo por:

  sudo dpkg -i python3-minimal_*.deb
  

Em seguida, certifique-se de que os comandos py3compile e py3clean sejam executáveis e sejam acessíveis a partir da variável PATH .
