一键安装使用指南及常见问题解决方案

月翘上枝头

请问我在ubuntu2004上使用一键安装报错如下该怎么解决呢，该错误是将系统自带的python3.8升级成11后开始出现的，我将系统的python3软链接给pyhon311了

@1597854501 我现在已经尝试过pip3 distro，修改系统变量将3.11的site-package路径加到pythonpath，再次运行一键安装时读取状态信息也可以识别到distro，但到了“已保存/tmp/fishinstall/tools/base.py"后运行还是会报错No module named distro，请问这是怎么回事呢

@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 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

我在树莓派ubuntu mate 16.04 上安装ros1-Kinetic无法定位软件包 9da69809-8171-4ddf-b87f-1f1e5453049f-c711e019ce12cd103a476cd601eb4e7.jpg

@2090127048 sudo pip install distro 或者 sudo pip3 install distro

@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。
