Debian HC4 NAS 無法解析任何主機

stackoverflow 和 linux 使用的新手，在 HC4 上設置了 NAS，目前正在嘗試設置 Steam 記憶體，在安裝 docker 後，我試圖安裝 network-manager，這導致我陷入了一個兔子洞，因為它返回了以下錯誤：

現在我使用 apt-get update 得到這些錯誤，並且 apt-get install network-manager 返回

Reading package lists... Done
Building dependency tree
Reading state information... Done
Package network-manager 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 'network-manager' has no installation candidate

因為我搞砸了很多，這是我的sources.list：

任何幫助或指示我的方向將不勝感激

好吧，一直在搞亂它，問題似乎是 eth0 的 OMV 配置和網路管理器配置的設置不同，因此在手動將兩者設置為相同的設置後，它能夠解析主機。
