Vorrei recuperare la password di root, ho trovato questo:
Booting into single user mode from GRUB
Follow these steps to reset the password when using GRUB:
* Reboot the system, and when you are at the selection prompt (See Fig. 2 below), highlight the line for Linux and press 'e'. You may only have 2 seconds to do this, so be quick.
* This will take you to another screen where you should select the entry that begins with 'kernel' and press 'e' again.
* Append ' single' to the end of that line (without the quotes). Make sure that there is a space between what's there and 'single'. If your system requires you to enter your root password to log into single-user mode, then append init=/bin/bash after 'single'. Hit 'Enter' to save the changes.
* Press 'b' to boot into Single User Mode.
* Once the system finishes booting, you will be logged in as root. Use passwd and choose a new password for root.
* Type reboot to reboot the system, and you can login with the new password you just selected.
Il problema è che quando cambio la password mi dice:
Authentication token lock busy.
