Usando o Debian 9.5, instalação nova. Eu quero instalar o mysql-server, mas me deparo com problemas de dependência.

  1. Best Answer

    Conforme indicado por sua apt policy perl perl-basesaída e apontado por jordanm , seu sistema possui a versão Buster do Perl, não a versão Debian 9. Então seu sistema não é realmente uma “instalação nova” do Debian 9.5; e como Perl é um componente tão importante de uma configuração Debian, é provável que existam muitos outros pacotes que foram atualizados para a versão Buster.

    Essa incompatibilidade de Perl é a razão pela qual você não pode instalar os pacotes MySQL.

    Presumo que esta seja uma instalação recente e, portanto, você não tenha investido muito nela; então a recomendação de jordanm para reinstalar é provavelmente a melhor solução neste caso. O Debian 9 e o Buster divergiram um pouco, então reverter pode se tornar bastante complicado, especialmente desde que você atualizou o Perl. Remover mccertamente não será suficiente.

    No futuro, não misture estável e teste. Se você encontrar um bug que o impeça de usar um pacote, registre um bug ( reportbug mc); se for grave o suficiente, pode se qualificar para uma atualização estável. Você também pode pedir um backport; que lhe daria a versão atual do Buster mc, reconstruída para o Debian 9.

  3. sudo apt install mysql-server Lendo listas de pacotes... Concluído Construindo árvore de dependências
    Lendo informações de estado... Concluído Alguns pacotes não puderam ser instalados. Isso pode significar que você solicitou uma situação impossível ou, se estiver usando a distribuição instável, alguns pacotes necessários ainda não foram criados ou removidos do Incoming. As seguintes informações podem ajudar a resolver a situação:

    Os seguintes pacotes têm dependências não atendidas: mysql-server : Depende: mysql-server-8.0 mas não será instalado E: Não foi possível corrigir problemas, você reteve pacotes quebrados. raja@raja-latitudee6400:~$ mysql-server default-mysql-server bash: mysql-server: comando não encontrado
