The steps for reseting root password on Debian machine through single user
mode is shown below.

boot options)
2. Once the GRUB screen is displayed, use the arrow keys to select the
boot entry showing kernel entry.
3. Press the key “e” to edit the entry
4. At the end of the kernel line add the word “1” or “single” (without the
double quotes)
5. After adding the entry press ESC key to go back to the grub screen
6. press the key “b” to boot this kernel in single user mode
7. You will be now logged in to the shell as root user
8. In the shell type: passwd root
9. It will prompt you for your new password and will ask you to confirm it.
10. Now root password has been reset, you can now reboot your server using
the command “reboot”
