Эта несправедливость будет управлять, вредят моей ОС Ubuntu после перезагрузки?

Я пытаюсь установить archlinux на Pogoplug.... Но я получил ошибку при высказывании, что разрешение было отклонено, потому что я не был корнем... Таким образом, я знаю для соединения "sudo" с корнем, но я не думал до впоследствии, что sudo мог бы только использоваться в качестве корневой команды для ubuntu OS... Я проверил папку каталога на диске Ubuntu, и конечно же я записал сценарий в него...

Это - команда, которую я ввел

/tmp$ sudo ./install_uboot_mtd0.sh

Это - то, что это выложило..........

Я наносил неисправимый ущерб своей ОС? Это все еще кажется прекрасным на данный момент, но я должен бояться перезагрузки?
