1. 修改配置
进入控制面板，进入“程序”子菜单：
单击“启用或关闭 Windows 功能”：
勾选“适用于 Linux 的 Windows 子系统”：
2. 下载 Ubuntu
进入 Microsoft Store，搜索 Ubuntu，这里会有多个搜索结果，注意下载标注出的版本：
安装完成后，即可在开始菜单找到 Ubuntu 的入口
首次进入 Ubuntu 系统，会要求设置用户名和密码。设置完成后，即可使用。
3. 修改软件源
在 Ubuntu 使用过程中，经常需要在线下载软件。由于网络问题，使用默认源会出现无法访问或网速很慢的问题，因此需要修改配置，使用国内软件源。软件源在 /etc/apt/sources.list 中配置，直接替换为以下内容即可：
1 # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to 2 # newer versions of the distribution. 3 deb http://archive.ubuntu.com/ubuntu/ focal main restricted 4 # deb-src http://archive.ubuntu.com/ubuntu/ focal main restricted 5 6 ## Major bug fix updates produced after the final release of the 7 ## distribution. 8 deb http://archive.ubuntu.com/ubuntu/ focal-updates main restricted 9 # deb-src http://archive.ubuntu.com/ubuntu/ focal-updates main restricted 10 11 ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu 12 ## team.

替换软件源后，要执行以下命令方能生效：
1 $ sudo apt-get update
4. 在 Ubuntu 子系统查看文件
我们可以在 Ubuntu 子系统中查看 Windows 文件。进入 /mnt 目录，即可看到本地磁盘。譬如 /mnt/d，就是 Windows 下的 D 盘。但 Windows 默认仅挂载了当前磁盘。
4.1 挂载磁盘
对于 U 盘、移动硬盘，需要挂载后使用。命令如下：
1 $ sudo mkdir /mnt/g # 创建挂载目录 2 $ sudo mount -t drvfs G: /mnt/g # 挂载 3 $ sudo umount /mnt/g # 卸载
4.2 挂载网络位置
我们的代码存储在服务器，并将其映射为 Windows 下的盘符，这种盘符在 Linux 子系统中默认是看不到的。但我们可以使用以下命令挂载网络位置：
1 $ sudo mkdir /mnt/android-server # 创建挂载目录 2 $ sudo mount -t drvfs '\192.168.10.3 enzhengzhi' /mnt/android-server/ # 挂载
