一键安装使用指南及常见问题解决方案

[1597854501]

@1597854501 更改etc/environment，添加pythonpath后，报错最终追溯到lsb_release，这是不是因为我修改系统默认python3.8到3.11导致的呢

[1597854501]

@1597854501 破案了，我找到报错文件，将开头的python3改成python3.8即可，推测原因为系统自带的这些功能默认用python3去软链接系统自带的python3.8，但我升级后将python3软连接给了python3.11，python3.11并不支持系统的ls_release等功能，故须像上述一样主动修改python3为python11，希望大家对我的教训引以为戒吧

@2960110040 等一下吧，系统里有其他的程序在占用dpkg。一般是系统的自动更新

描述：本来有一个foxy版本ROS，后来又一键安装了一个noetic的版本，然后在网上搜索后把foxy版本的删除了，现在又通过一键安装下载回来了现在每次打开终端之后，会先有这个询问：ros:foxy(1) noetic(2) ?
我输入 2 换行后，输入roscore，出现上述问题。

这是怎么回事，请问

[fxdzz]

大佬，这是什么情况

[1556319011]

@小鱼 请问运行ros2 doctor后输出
/opt/ros/humble/lib/python3.10/site-packages/ros2doctor/api/init.py: 118: UserWarning: Fail to call PackageCheck class functions.

All 4 checks passed
这是怎么回事，运行ros2 run demo_nodes_cpp talker
ros2 run demo_nodes_cpp listener
后可以收到消息

能问下图中的ModuleNotFoundError: No module named 'robot_vision_msgs'是什么问题
