我正在使用 Kubuntu 23.04。几天前我尝试升级到 23.10 版本。由于 grub-loader 位置存在问题，升级失败。无论如何。我设法将系统降级回 23.04，没有丢失任何数据。但从那天起，我一直面临网络问题。从那时起，我的网络就被禁用了。每次重启时，我都需要运行以下命令才能使其正常工作。
sudo ip link set enp0s31f6 up
sudo dhclient enp0s31f6
sudo systemctl restart smbd
sudo systemctl restart nmbd
是的，出于某种原因，我的 samba 共享也不起作用，除非我在每次重启时重新启动服务。作为临时解决方案，我可以忍受，但这太令人恼火了。我尝试了几种解决方案，但似乎都没有解决我的问题。
我尝试重新安装网络管理器，但没有成功。/etc/network/interfaces文件丢失，因此我创建并添加了以下代码。
auth enp0s31f6
auto lo enp0s31f6
iface lo inet loopback
iface enp0s31f6 inet dhcp
这也不起作用。
该/etc/netplan目录只有一个文件 -01-network-manager-all.yaml并且它包含以下内容。
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
我把它改成了
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
ethernets:
enp0s31f6:
dhcp4: true
但这也不起作用。
这是命令的输出sudo systemctl status NetworkManager。

我不知道还能尝试什么。如果您需要更多信息，请告诉我。即使使用命令启用网络后，我的网络状态图标仍是这样的。
我第一次看到缺少网络选项时必须手动创建它。创建它没有任何作用。
现在做什么？
