我的服务器安装 Ubuntu 20.04.3 LTS 运行时出现以下错误sudo netplan try：
An error occurred: 'NetplanApply' object has no attribute 'state'
Reverting.
Job for systemd-networkd.service failed because the control process exited with error code.
See "systemctl status systemd-networkd.service" and "journalctl -xe" for details.

我最初以为我做了一个小改动/etc/netplan/01-netcfg.yaml但又恢复到原来的错误仍然存在时我犯了一个错误。
我该如何解决这个问题？
