ahmet@ahmet:~$ systemd-analyze blame
30.049s NetworkManager-wait-online.service
您已将一个（或多个）网络接口配置为“ Require IPv4 (or IPv6) addressing for this connection to be complete”（在IPv4 Settings或IPv6 Settings`` tabs, or you've configured one of the "Automatic" choices in the常规`选项卡中；并且建立连接需要半分钟的时间。
您还应该查看journalctl -b 0并比较行间时间戳，以了解有关问题的更详细信息。
