安装好后，在VScode中连接不到容器：报错显示如下：

Retrying to download VS Code Server. [2069 ms] TypeError: Failed to fetch at I (vscode-file://vscode-app/usr/share/code/resources/app/out/vs/workbench/workbench.desktop.main.js:123:20340)

@1667296750 我遇到的事错误码127，对应的是其鱼香ros的脚本中的命令在环境中没安装，安装对应的命令就可以了。

@bsghiushfa_js_jdn我也遇到了，请问如何处理的

已解决
curl安装失败

sudo apt install curl -y

报错：

Depends: libcurl4 (= 7.68.0-1ubuntu2.25) but 7.68.0-1ubuntu2.22 is to be installed

解决：安装 aptitude

sudo apt-get install aptitude

使用 aptitude 安装curl

sudo aptitude install libcurl4

再重新安装ros

@YanHaBOYei请问大佬具体是怎么解决的呢

一键安装Cartographer失败：
Run CMD Task:[catkin_make_isolated --install --use-ninja]
[-][0.00s] CMD Result:code:127

Run CMD Task:[sudo chmod -R 777 cartographer_ws]
[-][0.00s] CMD Result:success

解决办法：脚本安装不成，需要手动编译，找到并进入自动安装所创建的工作空间cartographer_ws（其位于启动小鱼脚本的目录下），输入catkin_make_isolated编译工作空间，该命令支持存在非catkin包的工作空间的编译
catkin_make_isolated在~/.bashrc最后添加  source ~/cartographer_ws/devel_isolated/setup.bash

注意编译有4部分。
