Plex/Pihole 同时安装 Ubuntu 18.04 后出现 DHCP 问题

Plex/Pihole 同时安装 Ubuntu 18.04 后出现 DHCP 问题

通常,经过足够的时间,我的 Google-Fu 可以帮助我解决大多数 Linux 问题,但这个问题却让我困惑。

我最近尝试在运行 ubuntu 18.04.2 的 Plex 盒子上安装 Pihole。一切正常,但 pihole 无法可靠地阻止我想要阻止的主要内容(主要是我的 roku 上的 youtube 广告),所以我卸载了它。自从我这样做以来,我的 Plex 服务器就一直出现 DHCP 问题。

我已经找到了两种可以让事情正常运作的创可贴,但我想要一个适当的解决办法。

  1. 我可以编辑 resolv.conf 文件来添加我的路由器,或者将 cloudflare 添加为 DNS,这样可以解决所有问题。
  2. 我可以编辑 netplan .yaml 文件以强制以太网设备上的 DHCP,然后应用 netplan 配置。这也可以解决所有问题。

这两个修复程序的问题在于它们在重启后不会持续存在。我认为 Network-Manager 出了问题,但我不确定是什么问题,也不知道如何修复它。我猜这与 PiHole 没有真正的“干净”卸载选项有关。

我尝试了以下操作但没有成功:

  1. 拔下并重新插入所有网络硬件,并重新启动 Plex
  2. sudo apt-get -d --reinstall 网络管理器网络管理器-gnome

重启后 dig www.google.com 总是失败,ping -c 3 8.8.8.8 总是成功。尝试通过 8.8.8.8 访问 google 总是失败,除非应用其中一个顶级修复程序。

我不太确定需要做什么才能解决这个问题,但我感谢阅读本文的任何人的时间。我意识到我可能可以制作一些在启动时运行的程序来运行 netplan apply 命令,但我觉得有更好的解决方案。

谢谢!

更新 1:我尝试删除 lighttpd,并从 pihole 运行更新的 uninstall.sh。没有成功。此外,我修改了我的 *.yaml 文件以删除最后 3 行(ethernets、enp1s0 和 dhcp4)。修改后的 *.yaml 文件不再允许我之前的修复工作。

sudo netplan --debug apply以下是修改后的 *.yaml 文件的输出:

我无法通过任何常规渠道安装 resolvectl。

在用户修改以及 pihole 的安装/卸载之间,网络无法完全运行。

建议用户重新安装 Ubuntu,不要进行修改,不要重新安装 pihole。
