Ubuntu 20.04 服务器我遇到了一个奇怪的问题，我只能在虚拟机上遇到这个问题，而在任何裸机安装上都找不到它。
在完成全新安装并配置网络后，netplan 可以正常工作。但是，在运行 atp update 后，netplan 会中断。我收到的错误如下
root@wozdc01:/home/zeus# netplan try
Job for netplan-wpa-wlp4s0.service canceled.
An error occurred: Command '['systemctl', 'stop', 'systemd-networkd.service', 'netplan-wpa-*.service']' returned non-zero exit status 1.
Reverting.

无论对 yaml 文件是否进行了任何更改，都会发生此错误。

我已经多次进行全新安装并从头开始重新创建虚拟机。主机也已重新启动。
有任何想法吗？
