我在 Ubuntu 21.04 上安装和运行 docker 守护程序时遇到了一些问题。
在安装软件包期间我收到了以下失败消息：
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.
invoke-rc.d: initscript docker, action "start" failed.

当我尝试获取有关该问题的更多信息时，我dockerd --debug得到了以下信息：
failed to start daemon: Error initializing network controller: Error creating default "bridge" network: Failed to Setup IP tables: Unable to enable NAT rule: (COMMAND_FAILED: '/usr/sbin/iptables -w10 -t nat -I POSTROUTING -s 172.17.0.0/16 ! -o docker0 -j MASQUERADE' failed: iptables v1.8.7 (legacy): Couldn't load target `MASQUERADE':No such file or directory
我尝试清除已安装的所有 docker，然后重新启动并重试安装，但结果还是一样。
我也尝试过iptables这样重新安装sudo apt-get install --reinstall iptables但是它给出了与安装 docker 相同的失败：
sudo apt-get install --reinstall iptables

我在 Chromebook 笔记本电脑上的 USB 上运行 Ubuntu，使用呼吸如果它可以帮助我的情况。
我认为可能docker0没有设置但是运行时它似乎在这里ip link show：
lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

是不是我做错了什么？或者与我的设置有关？
