Ubuntu系统中，软件源文件地址为：/etc/apt/sources.list

1.备份原来的源，将以前的源备份一下，以防以后可以用的。

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

2.打开/etc/apt/sources.list文件，在前面添加如下条目，并保存。

sudo vim /etc/apt/sources.list（可将vim更换为自己熟悉的编辑器）

win10子系统 安装miniconda

wget http://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
chmod +777 Miniconda3-latest-Linux-x86_64.sh
bash Miniconda3-latest-Linux-x86_64.sh

按照指引安装即可（enter 阅读完条款后yes开始安装 enter安装在指定目录下，最后一步很重要，默认是no，我们要输入yes）

这时输入conda 命令会显示无该命令，因为在安装最后一步yes时系统会自动添加环境变量，修改了bashrc文件，我们需要更新一下文件，输入命令source .bashrc

source .bashrc

win10子系统 安装图形界面

安装桌面环境
apt install xubuntu-desktop
apt install xorg
apt install xfce4
安装并配置远程桌面服务xrdp

# 安装xrdp
sudo apt install xrdp
# 配置xrdp端口（将远程端口改为3390，避免和本机的3389端口冲突）
sudo sed -i ‘s/port=3389/port=3390/g’ /etc/xrdp/xrdp.ini
# 配置xsession
sudo echo xfce4-session >~/.xsession
# 重启xrdp服务
sudo service xrdp restart
使用win10的远程桌面连接工具
localhost:3390
