wsl中迁移ubuntu24.04后docker后无法启动的问题

发生原因

我将外网wsl2中的Ubuntu24.04迁移到内网（无网络）电脑中，发现原本安装的docker无法启动，

在使用 apt-get install docker-ce docker-ce-cli containerd.io重新安装后依然不行

NOTE：迁移后软件会失去注册信息，运行会提示命令未注册，所以需要重新安装。其实系统中已经包含了相关安装包，所以不会联网下载

原因

查看Docker的日志vim /var/log/docker.log显示如下的错误

shell 复制代码

iptables v1.8.10 (nf_tables):  CHAIN_ADD failed (No such file or directory): chain PREROUTING
 (exit status 4))

原因是由于迁移后ubuntu系统使用了iptables-nft，而WSL2不支持导致的。

修复

修改为iptables-legacy即可

shell 复制代码

 root@DESKTOP-5DTRJV0:/home/friday/apt-offline# update-alternatives --config iptables
There are 2 choices for the alternative iptables (providing /usr/sbin/iptables).

  Selection    Path                       Priority   Status
------------------------------------------------------------
* 0            /usr/sbin/iptables-nft      20        auto mode
  1            /usr/sbin/iptables-legacy   10        manual mode
  2            /usr/sbin/iptables-nft      20        manual mode

Press <enter> to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/sbin/iptables-legacy to provide /usr/sbin/iptables (iptables) in manual mode
