Ubuntu 22.04 LTS升级后开机卡在「Failed to start Wait for Network to be Configured」错误，求助解决方法

我刚升级了我的Ubuntu 22.04 LTS机器，现在开机时卡在黑屏界面，只显示：

[FAILED] Failed to start Wait for Network to be Configured

不过我还能通过SSH访问这台机器。运行systemd-analyze blame得到以下结果：

我尝试过修改/etc/netplan/01-netcfg.yaml，添加了optional: true配置，但重启后问题依然存在。我的netplan配置文件内容如下：

network:
version: 2
renderer: networkd
ethernets:
enp0s3:
dhcp4: yes
optional: true

ls /etc/netplan/的输出是：

01-netcfg.yaml

有没有不用重新安装系统的解决办法？非常感谢！——Evert

问题解决记录 #

后来我找到问题所在了！不知道为什么升级后Nvidia驱动被卸载了，我通过命令行重新安装了Nvidia驱动，现在已经能正常进入GUI了，所有功能都恢复正常。

谢谢大家的关注！——Evert
