não é possível instalar o gcc-multilib após atualizar para o 14.04

Question

Atualizei recentemente de 12.04 para 14.04. Depois de atualizar as coisas começaram a quebrar.

Estou recebendo crt1.o: Nenhum arquivo: Nenhum arquivo ou diretório . Então, eu tentei instalar o gcc-multilib, mas isso também está causando erros.

$ sudo apt-get install gcc-multilib

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 gcc-multilib : Depends: gcc-4.8-multilib (>= 4.8.2-5~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Eu tentei

Eu tentei postar a saída dos seguintes comandos, mas não consigo fazer isso.

cat /etc/apt/sources.list
cat /etc/apt/sources.list.d/*

Como posso resolver isso?

Answer 1

Eu não uso frequentemente aptitude , mas em caso de problemas com diferentes versões gcc e dependências não satisfeitas, apt-get é algumas vezes incapaz de corrigir problemas dizendo "você realizou pacotes quebrados"

Nesse dia, você deve instalar o aptitude e tentar instalar o pacote que deseja. Ele mostra claramente todas as dependências e faz não apenas uma sugestão.

As primeiras sugestões são geralmente as mesmas que o apt-get faria, mas se você clicar em "não", o aptitude mostrará outra, que talvez atenda melhor às suas necessidades.

Tente!

A resposta está um pouco atrasada, mas eu sempre procurei por problemas como esses e fiquei feliz com as diferentes soluções.

    

Answer 2

O comportamento observado parece resultar de um bug legítimo descrito em

O relatório acima citado contém minha solução alternativa de curto prazo que renderizará apt-get novamente.

Acredito que, em essência, o sudo apt-get -f install falha é uma duplicata desta questão.
