Ubuntu21.04 NetworkManager.service失败
Ubuntu21.04 NetworkManager.service失败
提问于 2021-08-18 14:09:31
我正面临NetworkManager服务的某些问题。它随机失败，我没有互联网连接，除非我重新启动机器。使用sudo service NetworkManager restart或sudo systemctl restart systemd-networkd重新启动以前用于解决问题的D0服务，但它们现在不起作用。重新启动机器是恢复互联网连接的唯一选择。
当我试图重新启动NetworkManager服务时，就会发生这种情况：
$ sudo service NetworkManager restart
Failed to restart NetworkManager.service: Unit NetworkManager.service failed to load properly: Transport endpoint is not connected.
See system logs and 'systemctl status NetworkManager.service' for details.检查systemctl状态，我得到以下信息：
$ systemctl status NetworkManager.service
● NetworkManager.service - Network Manager
Loaded: error (Reason: Unit NetworkManager.service failed to load properly: Transport endpoint is not connected.)

有人能帮我找出什么是失败的，以及如何重新启动失败的组件，以便恢复我的互联网连接，而不必重新启动我的机器。

在发出Transport时，我也遇到了同样令人困惑的systemctl restart NetworkManager端点没有连接到错误，并且能够使用systemctl deaemon-reload (猜测)解决它。
