我应该允许突触降级软件包吗？

  • 772

在 synaptic 上，我想安装 dkpg-dev，但 synaptic 需要为此降级 libdkpg-perl。允许这样做是个好主意，否则我会遇到包裹损坏的问题。在这种情况下，您使用什么经验法则？我有一个新安装的 Ubuntu 14.04。我怎么会遇到这个？谢谢你。.

这是我的 sources.list：

我的 /etc/apt/sources.list.d/ 是空的

实际上，我重新安装了 libdkpg-perl。它是

“安装版本：1.17.5ubuntu5.3 和最新版本：1.17.5ubuntu5”

我不确定我是怎么做到的。是因为我的 sources.list 吗？

重新安装后，我有：

“安装版本：1.17.5ubuntu5 和最新版本：1.17.5ubuntu5”

相当于降级

  1. Best Answer

    在终端中执行以下命令，以更新包源：

    sudo apt-get update

    然后再次运行安装dkpg-dev：

    sudo apt-get install dkpg-dev

    基于你的sources.list和一个空的/etc/apt/sources.list.d，接受降级应该没有问题。

  2. 你可以允许它，这不是问题。synaptic 提供的软件包是您要安装的软件包的依赖项。
