无法在 Ubuntu 20.04 LTS 中执行“netplan apply”命令

netplan apply当我以 root 用户身份执行该命令时，该命令返回一些错误。

root@szyf1272:/etc/netplan# netplan apply

答案1

systemd 响应以下命令返回此错误：

systemctl stop --no-block systemd-networkd.service 'netplan-wpa-*.service'

这将检查是否/run/systemd/system存在并且可以访问。

在正确启动的 Ubuntu 20.04 系统上，这始终是正确的。

我不知道您做了什么导致该目录不存在，但是这样的系统已经严重损坏且无法支持。
