记一次Ubuntu系统修改自带Python软连接的错误

操作系统;Ubuntu 20.04

刚装上系统，看了一下有Python，由于是Python3.10，所有想将Python3命令修改为Python命令，感觉更顺手，于是就把  /usr/bin/目录下的Python3软连接名称修改成了Python

 

命令：sudo apt-get upgrade

 修改之后发现apt命令出问题了，网上找半天说和info文件夹有关，照着弄一直没有弄好，由于是新装的系统，只动了系统里面的Python所以我改回来就正常了

总结：Ubuntu中自带的Python没必要不要去动，需要直接用Python再创建一个软连接即可
