• If you haven’t set a password before, then it should be the default one: empty. Then, to use sudo you will need to set one by using passwd command.

    In case if the password was set in the past: the only way would be to run factory reset, or restore from image.

    • Booting from any rescue Linux system and removing or editing /etc/shadow in the overlay partition would work as well. No need for a factory reset.

      • You have to boot from another OS, mount the drive, then do it. If its LUKS protected you gotta open that first.

  • Have you installed anything else on your deck already in desktop mode, like Decky loader, emudeck, cryoutilities/etc?

    Some of those have an option to set a default password to something like “deck”. If you clicked through the setup on those it might have set a password without you realizing.

    edit: Decky loader can temporarily set the password to “Decky!”. It’s supposed to remove the temp password after installation, but that’s worth trying if you installed Decky. Right now I don’t see a default password for emudeck or cryoutilities, but it’s possible other deck install scripts might set one.
