我对 Linux 还不太熟悉，所以我想我应该从 Kubuntu 开始“简单”的学习。我遇到的问题是 Skype 无法安装。它不在 Muon Discover（软件中心）中，并且无法通过 Konsole 添加要安装的 repo。
因此，这是我收到的错误：
tyler@tyler-GA-78LMT-USB3:~$ sudo apt-get install skype
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package skype:i386 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'skype:i386' has no installation candidate
我也刚刚尝试下载 .deb 文件并通过 Konsole 安装它，但没有成功。
但也许更大的问题是，当我尝试输入“sudo apt-get update”时出现以下错误：
tyler@tyler-GA-78LMT-USB3:~$ sudo apt-get update

那么这是怎么回事呢？我多次修改了 source.list 文件。这是当前格式：

非常感谢您的帮助。

启用合作伙伴存储库
然后通过更新索引sudo apt-get update并使用sudo apt-get install skype它进行安装。
Trusty 中主服务器的合作伙伴存储库如下所示
deb http://archive.canonical.com/ubuntu trusty partner
您应该将其更改trusty为vivid或您的特定发布名称。
