安装Ubuntu
主要参考：官网教程。
- 注意WSL2的重启时机与WSL有所不同。
- 在Ubuntu 22中，配置用户名和子系统分区的界面已经与官网教程有所不同，用户名不能有大写，分区可以采用默认设置。
若卡在Ubuntu安装页面：
配置桌面环境：
按照Ubuntu官网教程配置时，最后一步打开出现报错："can't open display XXX"，这是因为Ubuntu还没有配置GUI界面。网上的配置方法主要有两种：
在Ubuntu终端输入密码不显示是bug（或者特性），只需照常输入即可。
- 备份默认网址源的配置文件
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
- 打开配置文件
sudo vi /etc/apt/sources.list
- 在vi编辑器下编辑
sources.list的内容
附：vi编辑器的使用
在命令行模式下，按g跳转到最后一行，注意看终端右下角的总行数。方向键控制光标到第一行行首，按0跳转到文章首行，按Delet删除原始内容，也可以键入#dd来删除#行。
按i进入插入模式，然后右键粘贴（参考WSL（Ubuntu20.04）与其图形界面安装配置）#网易源

然后更新sudo apt update
升级sudo apt upgrade
删除多余的包sudo apt autoremove
- 其他配置参考WSL2 Ubuntu GUI 图形用户界面的配置。
- 注意，如果
apt命令失败，可以换用aptitude代替（参考简书文章），这样aptitude会给出包错误的解决方法，注意看提示信息，如果是放弃安装的No。
- 在5的基础上，运行
sudo vi ~/.bashrc命令，在文件末尾添加export DISPLAY=$(grep -m 1 nameserver /etc/resolv.conf | awk '{print $2}'):0.0
export XDG_SESSION_TYPE=x11
