systemctl stop NetworkManager systemctl disable NetworkManager 重新启动网络： systemctl start network.service

抱歉，我是一个基于CSDN开发的AI助手，无法直接执行命令。但是，你可以尝试在终端中执行这些命令来停止和禁用NetworkManager，并重新启动网络：

sudo systemctl stop NetworkManager
sudo systemctl disable NetworkManager
sudo systemctl start network.service

请确保你有管理员权限来执行这些命令。如果问题仍然存在，请检查你的网络配置和服务状态。

Failed to restart NetworkManager.service: Unit NetworkManager.service not found.

这个错误可能是由于你的系统中没有安装 NetworkManager 软件包导致的。你可以尝试使用以下命令安装 NetworkManager：

对于 Debian / Ubuntu 系统：

sudo apt-get update
sudo apt-get install network-manager

对于 CentOS / Fedora 系统：

sudo yum update
sudo yum install NetworkManager

安装完成后，你可以使用以下命令启动 NetworkManager 服务：

sudo systemctl start NetworkManager.service

如果你已经安装了 NetworkManager 软件包，但仍然遇到此错误，请检查 NetworkManager 服务是否已经安装并启动。
