大家好，
新的一天，我的家庭服务器上新的 Linux 冒险：
Can resolvconf-pull-resolved.path be blocking my servers internet connection ?
背景信息：
我最近按照 apt update && apt upgrade 的例行执行将我的服务器更新/升级到最新更新并开始工作。
后来我尝试使用我拥有的静态 IP 地址 ssh 连接到我的服务器，但没有连接。我想我需要重新启动服务器，然后我就可以再次运行了，然后又跑开了。过了一会儿，我再次 ssh 连接到服务器，仍然没有找到与主机的连接。那时我开始担心了。
启动系统时看着屏幕，我注意到第一个 [FAILED] 被 resolvconf-pull-resolved 并且稍后无法带来 op 网络（第二个 [FAILED]）。
尝试了一些已经类似此页面的内容，但没有帮助。
尝试了 journalctl -xe，结果显示很多红色内容。但我似乎没有弄清楚为什么会发生这种情况。
所以现在我想知道是否存在 2 个问题，或者 1 个问题导致另一个问题。由于我对 Linux 了解一些基本知识，这远远超出了我的知识范围。
非常感谢您的任何指点，并想提前感谢您提供的帮助。
我已经有了一个新的实时 USB 记忆棒，用于重新安装服务器，但是话又说回来，这有什么乐趣呢？
PS：其他情报可以在我的服务器上找到这里。
我对 libtevent 进行了更新，希望没有版本冲突
那么，有人可以再次解释一下这个问题吗？

答案1
因此，在对服务器进行更多研究后，我的网络设备也出现了错误。由于上述问题不太简单，所以我想看看另一个故障：
sudo systemctl status networking.service 返回此信息：

和
sudo networkctl 列表
给我
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier unmanaged
2 eth0 ether off unmanaged
2 links listed.
由于我不是 IT 人员，所以我花了一些时间才意识到我的网络没有打开。

那时我以为网卡坏了

但这表明网卡没有任何问题，所以现在我认为一定是其他地方出了问题。
然后我就这么做了（不知道在哪里找到的）
sudo dhclient
这给了我：
/etc/resolvconf/update.d/libc: Warning: /etc/resolv.conf is not a symbolic link to /run/resolvconf/resolv.conf
所以事情对我来说变得复杂了，因为我不确定这意味着什么。出于某种原因，也许是因为我遵循了某处的指示。
networkctl 状态
然后给了我：
● 2: eth0
Link File: /lib/systemd/network/99-default.link
Network File: n/a
Type: ether
State: routable (unmanaged)
Path: pci-0000:02:00.0

fe80::21b:fcff:fe5a:3c7e
Gateway: 192.168.178.1 (Cisco SPVTG)
其中状态：可路由（未管理）变为绿色。
尝试 ping 8.8.8.8，立即得到答复。然后我以为我已经解决了问题，执行了 apt-update && apt-upgrade，一切顺利，重新启动 > 没有互联网
像我这样白痴
再次执行 sudo dhclient ，结果相同：
● 2: eth0
Link File: /lib/systemd/network/99-default.link
Network File: n/a
Type: ether
State: routable (unmanaged)
Path: pci-0000:02:00.0

Gateway: 192.168.178.1 (Cisco SPVTG)
互联网再次备份
做过
systemctl status resolvconf.service

这个故事中有趣的部分是我刚刚意识到最后一行与 sudo dhclient 返回的代码相同。
因此，resolvconf 的情况显然是由于 eth0 没有启动而导致的。
这个故事可能本来可以短得多，但有些管理员可能会缩短它:)或者纠正我的语法。
