最近我像往常一样打开Skype，看到了这个：

我所有的联系人列表都被复制了。我猜这是 Skype 中的一个错误。

1. 如何清除多余的联系人列表条目？
2. 如何防止这种重复发生？

Skype 桌面版是 7.18.85.112

不幸的是，在我的 Debian 8 中，jessie systemctl 根本不起作用。

每个systemctl命令都会导致：

Failed to get D-Bus connection: Unknown error -1

系统状态 udev

无法获得 D-Bus 连接：未知错误 -1

我该如何解决？

我会很感激你的帮助。

当我kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml --validate=false按照这里的描述做

我得到：
