22.04 桌面启动时出现“正在运行启动作业，等待网络配置”

这是在 raspberry pi 4b、台式机（不是服务器、虚拟机等）上运行的 22.04。只是一个简单的台式机。它已经运行了一年多，但大约一个月前更新后，现在我收到了上述延迟启动的消息。启动后，网络似乎运行良好。我没有对网络设置做任何事情；这只是发生在另一台类似的机器上，直到今天更新之前，这台机器也运行良好。

greenman@snowball:~$ networkctl
IDX LINK  TYPE     OPERATIONAL SETUP      
  1 lo    loopback carrier     unmanaged

  2 eth0  ether    no-carrier  configuring

  3 wlan0 wlan     routable    unmanaged

3 links listed.

感谢您的建议，再次为格式问题道歉。在花了一天的大部分时间尝试浏览 systemd 错综复杂的命令结构后，似乎当我使用网络管理器管理我的网络端口时，某些更新决定尝试安装 systemd-networkd 来执行相同的操作。厨房里的两位厨师无法工作，因此：

sudo systemctl disable systemd-networkd.service

结束了整个噩梦。再次感谢您的帮助。

请https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/2036358对于稳定版本更新中已知的 systemd 回归问题，现在应该已经解决。
