    • After sudo su type your user’s password to enter super user then try the procedure on it.

      Works on my Linux mint 19.3 cinnamon :)

    • sudo passwd root works in some cases in the single-line command given.

      If the system’s superuser and other system users are the same people, passwords for superuser and regular username with restricted permissions are different in both users.

      I was resetting the root password on my Linux Mint 20.1 Ulyssa 64-bit version earlier last month with a single-line comment

      $ sudo passwd root 
      

      I think it worked very well.

      Before I used Ubuntu variant Lubuntu 14 on my second Linux laptop brand new in the year 2005 and there was the solution by mounting your hard drive with reading and writing permissions before changing the password command in Recovery mode but like in this James Kiarie great blog post article, you have to reboot your system holding SHIFT-key.

      It’s not necessary anymore for Mint users’ to reboot the whole system I think nowadays.

      This option and possibility to reset admin’s and superusers passwords in Ubuntu and Mint make it there’s no way to use Mint or Ubuntu system in industrial use due to security issues what makes sense when Linux/Unix System Administration comes to industrial zone (For ie. Small company’s server for it needs excluding traffic outside of office’s IT Infra).

  1. Does not quite work in Linux Mint 20 in single-user mode,

    The solution, after doing: passwd root
    do passwd your username

    with your username (no caps) I suggest you set both the same password.

  2. I have an added problem it says I was successful at changing my password but it still doesn’t work to log in. Is there a way to eliminate the password? I have not been able to get into my computer for a while now.

  3. Running Linux Mint 20 updated on 1/1/2021 in single-user mode requiring entry of user password. Followed your instructions exactly and everything went as described. Entered and confirmed a new password and got “Password Successfully Changed”.

    Used F10 key to continued booting. Got Enter the Password login screen and entered the new password. It said “the wrong password” I tried the new password several times and still got “the wrong password” — So I entered the OLD password and log-in proceeded as normal. Did several reboots including one from the power-down state — no luck. The new password is not recognized by the OLD password is.

    So, as of January 1, 2021, the Grub modification of the root password does not seem to work. There is only one user on the system, so unless I don’t understand something the root password should be the Username password, right?
