Debian HC4 NAS无法解析任何主机

Question

对于堆栈溢出和linux的使用，在HC4上有一个NAS安装程序，目前正在尝试设置一个蒸汽缓存，在安装了docker之后，我试图安装网络管理器，因为它返回了错误，因此导致我掉进了一个兔子洞：

现在，我得到了apt-get更新的这些错误，apt-get安装网络管理器返回。

This may mean that the package is missing, has been obsoleted, or

E: Package 'network-manager' has no installation candidate

因为我经常搞砸这件事，下面是我的sources.list：

Answer 1

好的，它一直在混乱，问题似乎是eth0的OMV配置和网络管理器配置设置不同，所以在手动将两者设置为相同的设置之后，它就能够解决主机问题。
