You will have to install the above packages yourself.

Ele diz que tenho que instalar esses pacotes sozinho, mas como fazer isso?

Quando estou tentando sudo apt-get install <some_package> , ele me diz (exemplo para gcc-4.8-multilib):

gcc-4.8-multilib : Depends: lib32gcc-4.8-dev (= 4.8.2-19ubuntu1) but it is not going to be installed
                    Depends: libx32gcc-4.8-dev (= 4.8.2-19ubuntu1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Alguém pode me ajudar a resolver todos esses pacotes de instalação?

Answer 1

abra seu terminal e digite como

sudo apt-get autoclean
sudo apt-get autoremove
sudo apt-get update
sudo apt-get dist-upgrade

sudo apt-get autoclean limpa o repositório local de recuperados arquivos de pacote no /var/cache/apt/archives . A diferença é que ele apenas remove os arquivos do pacote que não podem mais ser baixados, e são em grande parte inúteis.

sudo apt-get autoremove usado para remover pacotes que foram automaticamente instalados para satisfazer as dependências de outros pacotes e agora não são mais necessários.

autoclean e autoremove usados para garantir que não haja pacotes desnecessários que possam afetar seu sistema.

sudo apt-get update atualiza a lista de fontes e ressincroniza os arquivos de índice de pacotes de suas origens.

sudo apt-get dist-upgrade dist-upgrade, além de executar a função de atualização, também lida de forma inteligente com dependências variáveis de pacotes

    

Answer 2

Pelo menos alguns dos seus pacotes gcc são manualmente instalados e correspondem a uma versão mais recente que a do Ubuntu 14.04. Para instalar o g++-multilib e suas dependências, você precisará fazer o downgrade desses pacotes para as versões nos arquivos.

Comece executando

sudo apt-get install gcc-4.9-base=4.9-20140406-0ubuntu1

e trabalhe o seu caminho a partir daí ... Isso deve lhe dar um monte de erros que lhe dirão quais outros pacotes você precisa fazer o downgrade.

Para fazer o downgrade dos pacotes, você precisa executar apt-cache policy em cada um para determinar qual versão está no arquivo (essa é a versão com trusty URL) e adicioná-la à linha sudo apt-get install acima; então você acabaria com

sudo apt-get install gcc-4.9-base=4.9-20140406-0ubuntu1 package1=version1 package2=version2 ...

Alternativamente, você poderia apenas remover gcc e todos os pacotes relacionados e reinstalá-los.

Você tem outras bibliotecas com versões instaladas manualmente, portanto, pode ser necessário um pouco de trabalho para restaurar o sistema para corresponder aos arquivos.

    

Answer 3

Minha solução: no software e na atualização do ubuntu, localize o painel "atualizações", selecione Atualização de segurança importante e Atualizações recomendadas, então funciona bem, espero que ajude!
