@lxj The other thing is the root file system in UT is read only for security, see here so using sudo may break the system as you have to make it writeable.

Yes, but if I don't have root permission, I can't do anything, but I can't change the root password,,,,,,,

@lakotaubp yes OK

Why can't I change the root password and the terminal can't update and install software

@mrt10001 still not

@mrt10001 said in sudo passwd root passwd:认证令牌操作错误？？？？helphelp:

Have you tried resetting the operating system, or even re-installing? From past experience on Linux changing the root password can be hit or miss.

I reinstalled it, still the same

终端用不了阿,无法更新,修改不了root密码,

What if the root password cannot be changed? help me
