Ubuntu 21.04 NetworkManager.service 失败

我在使用 NetworkManager 服务时遇到了一些问题。它会随机失败，除非我重启机器，否则我将无法连接互联网。以前，使用sudo service NetworkManager restart或重启 NetworkManager 服务sudo systemctl restart systemd-networkd可以解决问题，但现在它们不起作用了。重启机器是恢复互联网连接的唯一选择。

当我尝试重新启动 NetworkManager 服务时发生这种情况：

$ 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，我得到了以下信息：

$ systemctl status NetworkManager.service
● NetworkManager.service - Network Manager
     Loaded: error (Reason: Unit NetworkManager.service failed to load properly: Transport endpoint is not connected.)
     Active: inactive (dead) since Wed 2021-08-18 09:05:22 IST; 12min ago

我已将journalctl -xe日志发布于：https://pastebin.com/vi8f4eSj

有人能帮助我找出故障所在以及如何重新启动故障组件，以便恢复我的互联网连接，而无需重新启动我的机器。

我也遇到了同样令人困惑的事情传输端点未连接发行时也出现错误systemctl restart NetworkManager，并且能够使用（猜测）解决它systemctl deaemon-reload。
