Foreword:
I was really bored in the library study. In order to excite myself, I started to pay attention to obtaining other people's mobile phone hotspot passwords, (just want to experiment with foreign gods) secretly went to "foreign" to watch videos and learn. Removed I replaced the previous kali linux with the 2020 version of kail linux, thinking about turning on the wireless network card monitoring, only to find that I don't have administrator rights, hehe hehe!
So this is ah:
The default user created by the new version of kali linux is a normal user, and you need to set the administrator password for root.
Setup process:
sudo passwd root
输入新的密码(两次)
su root //切换用户,如果有必要可以选择重启设备
to sum up:
It’s strange how the latest version of Kali Linux has the process of setting root permissions by itself.
