Devo permitir que os pacotes sejam rebaixados pelo synaptic?

Question

No synaptic, eu quero instalar o dkpg-dev, mas o synaptic precisa fazer o downgrade da libdkpg-perl para isso. É uma boa ideia permitir isso ou vou me deparar com problemas com pacotes quebrados. Que regra geral você usa nesses casos? Eu tenho um Ubuntu 14.04 recém-instalado. Como eu me deparo com isso? Obrigado. .

-------------------------------- EDIT 2

Na verdade, eu instalei a libdkpg-perl. Foi

"versão instalada: 1.17.5ubuntu5.3 e mais recente: 1.17.5ubuntu5"

Não sei bem como chegar a isso. É devido a minha sources.list?

Depois de reinstalar, tenho:

"versão instalada: 1.17.5ubuntu5 e mais recente: 1.17.5ubuntu5"

É equivalente a um downgrade

.

    

Answer 1

Execute os seguintes comandos em um terminal, para atualizar as fontes de pacotes:

sudo apt-get update

Em seguida, execute a instalação de dkpg-dev novamente:

sudo apt-get install dkpg-dev

Com base no seu sources.list e um /etc/apt/sources.list.d vazio, aceitar o downgrade não deve representar nenhum problema.

    

Answer 2

Você pode permitir isso, isso não é um problema. As ofertas sinápticas dos pacotes são as dependências dos pacotes que você deseja instalar.
