Root Password Reset

Jump to solution

Hi All,

Good Day..!

I came to know about debug-shell service which doesn't require password to get root shell prompt.

Can we use the debug-shell to reset the root password instead of going through rescue kernel?

Note: I was able to reset the root password via debug-shell

Thanks

Yes it can be done.  It is advisable to           mask the service / disable debug-shell.service     after you've finished debugging your boot problems.

For people who are wondering how to do it, please follow below instruction.

1. Interrupt the boot loader by pressing any key (except enter) while booting and press to edit the default kernel selection

2. Move your cursor to the end of line which begins with word linux and append systemd.debug-shell

3. Press Ctrl+x to save and continue the boot

4. Press Ctrl+Alt+F9 to get the debug shell and then proceed to change the password

5. Press Ctrl+Alt+F1 to switch back to default console TTY1 and login with the new password

6. Run systemctl stop debug-shell.service or perform system reboot to stop the debug-shell
