If you accidentals locked-out or want to change the root/user password at any cost - you can reset it.
Side effect & Note: Previous users
login.keyring
will not work. Hence, you will loss all previously saved wifi/network drives as well as Google Chrome profile settings (until you remember the old password and unlock it).
To reset follow the following steps.
- Reboot pc
- Hold SHIFT during boot to start GRUB menu
- Highlight your image and press E to edit GRUB config (change will reset after reboot)
- Find the line starting with “linux”
- Append
rw init=/bin/bash
at the end of that line - Press CTRL + X to continue the boot
- Change password with command
passwd USERNAME
- Reboot with CTRL+ALT+DEL
- Log in using the new password
If you want to backup your keyring file to try unlocking it later save the following file:
/home/user/.local/share/keyrings/login.keyring
