Question

SO: Ubuntu 14.04, amd_x64.

No entanto, comandos como update e clean funcionam bem.

Não sabe como resolver o problema. Dê uma olhada na minha sessão de terminal.

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libpython3.3 : Depends: python3.3 (= 3.3.6-1+trusty1) but 3.3.2-7ubuntu4 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

$ sudo apt-get -f install -y

Aparentemente, ninguém sinalizou as diferentes versões dos pacotes Python como conflitantes. Portanto, apt-get não pode resolver corretamente as dependências e substituir, remover e adicionar os pacotes na ordem correta.

Como solução alternativa, você pode remover os pacotes conflitantes manualmente enquanto sobrescreve os problemas de dependência. Você pode precisar brincar um pouco com a ordem (como eu não sei exatamente as cadeias de dependências aqui), mas a idéia geral é rodar

dpkg -r --force-depends libpython3.3-minimal libpython3.3-stdlib

Isso pode travar / interromper a execução de aplicativos ou serviços do sistema com base no Python 3.3 e talvez seja necessário reiniciá-los após a atualização.
