Suponho que preciso desinstalar a versão 2.18-4 sem remover dependências e versões mais antigas do pacote. Então, como fazer isso?

    

Answer 1

Você pode usar apt-get para instalar uma versão específica do pacote, desde que esteja em um arquivo que o apt saiba. Na% man_de% manpage:

apt-get

Por exemplo, você poderia fazer:

A specific version of a package can be selected for installation by following the package name with an equals and the version of the package to select. This will cause that version to be located and selected for install. Alternatively a specific distribution can be selected by following the package name with a slash and the version of the distribution or the Archive name (stable, frozen, unstable). Note que você pode precisar fazer alguma resolução de dependência por conta própria nesse caso, mas se houver algum problema, o apt-get informará o que está causando isso. No meu sistema 11.10, eu precisaria fazer o seguinte para que isso funcionasse:

sudo apt-get install apache2=2.2.20-1ubuntu1 '
