篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了win11安装的Ubuntu20.04子系统出现System has not been booted with systemd as init system (PID 1)问题的解决流程相关的知识，希望对你有一定的参考价值。

第五步：点击连接，开始进入Linux子系统编辑

第六步：切换到的账户的输入密码，并点击认证

第七步：成功进入Ubuntu20.04

三、尾言

一、前言

由于研究方向是无人机路径规划需要用到ros机器人操作系统，我就在Win11系统的电脑上安装了一个Ubuntu20.04LTS版本的Linux子系统。之后我在打开linux子系统的情况下把自己的win11主系统给关机了，后来再把电脑开机通过远程桌面连接去访问Linux子系统时出现了下面的错误：

System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: 主机关闭

二、具体解决方法

按照下面的操作就行了：

第一步：切换root用户至自己账号

自己账号就是安装ubuntu20.04时自己创建的那个用户账号

运行命令：

root@LAPTOP-S0G7C3PS:~# su renlinchao

现象：

第二步：重新安装xrdp

sudo apt-get install xrdp

现象：

[sudo] renlinchao 的密码：
正在读取软件包列表... 完成
正在分析软件包的依赖关系树
正在读取状态信息... 完成
xrdp 已经是最新版 (0.9.12-1)。
升级了 0 个软件包，新安装了 0 个软件包，要卸载 0 个软件包，有 0 个软件包未被升级。

第三步：重新配置端口并启动xrdp

运行命令：

sudo sed -i 's/3389/3390/g' /etc/xrdp/xrdp.ini
echo "gnome-session" > ~/.xsession
sudo systemctl restart xrdp
sudo systemctl status xrdp

现象：
