我无法在我的 Ubuntu 14.04 64 位系统上安装许多不同类型的软件包。
我已经运行了命令
sudo dpkg --add-architecture i386
正如许多相关问题所建议的那样，但是当我运行
sudo apt-get install skype
我得到：
Reading package lists... Done
Building dependency tree
Reading state information... Done

Steam 也失败了：

另外，甚至我认为像 samba 这样简单的东西也无法安装：

以下是未注释的行/etc/apt/sources.list：

我相信这与 Ubuntu 14.04 中的“新”多架构系统有关（我的上一个系统运行的是 13.04），但我真的不知道该怎么做才能解决这个问题。我见过许多建议，涉及将旧发行版中的软件包强行塞入 14.04，但除非万不得已，否则我不想这么做。
我安装的唯一 PPA 是 Google Chrome 的 PPA。
我该如何解决？
答案1
对于 Skype 和 Steam，软件包来自 Canonical 合作伙伴的 repo，正确的代码行是：
deb http://archive.canonical.com/ubuntu trusty partner
您的列表中缺少ubuntuURL 末尾的 。
进行此更改后，请重试apt-get update。您应该使用该 software-properties-gtk程序从这些预先列出的存储库中进行选择。您可以通过Sources在 Dash 中输入来运行它。
我不确定samba。在这种情况下，错误是您持有破损的包裹。我建议apt-get install -f。
