ubuntu默认的软件园在国外，国内访问就是龟速，严重影响使用！下面说说更换国内软件源的方法。
我们来切换到软件仓库的配置目录：
cd /etc/apt
备份原来的仓库配置
cp sources.list sources.list.back
使用nano文本编辑器打开配置文件：
nano sources.list
把光标放到第一行，按住ctrl加k清空文字；
然后复制新的仓库地址，见闻莫；
在命令窗口内鼠标右键执行粘贴操作，粘贴玩后可以用光标键浏览；
检查无误后按ctrl加x，在输入y回车保存配置文件
然后执行：
apt update
换源工作就完成了。
注：若命令无法执行，可在命令前加sudo或用su切到root账户操作。
地址，从中选一个即可

出现这样的问题，一般都是因为子系统的重装或系统所在路径改变造成的。在wsl.exe中注销之前的子系统，重新安装即可解决。
解决方法：
打开管理员cmd或powerShell
输入以下命令
wsl --list --all
这条命令用于列出已注册的子系统。
然后输入
wsl --unregister "上面显示的系统名称不含引号"
再去启动新安装的子系统就好了。

由于商店可以获取到的wsl子系统较少，这里贴上wsl子系统的手动下载地址。下载回来是微软商店的安装包文件，可以回车安装，若无微软商店或想放到其他分区，直接暴力拆包就可以使用。
wsl子系统总共有6个，分别是ubuntu、debian、fedora、kali、SUSE和openSUSE。
