Проблема, устанавливающая Ubuntu на Chromebook

Я пытался установить Ubuntu на своем Chromebook HP 14 с помощью гренка. Я следовал учебному руководству на CNET, но я сталкиваюсь с проблемой. Когда я ввожу команду sudo -e ~/Downloads/crouton -t unity все, что я получаю, является этим большим сообщением.

Даже когда я пытаюсь открыть Crouton для просмотра файлов, он сделал, я получаю это большое сообщение. Я уже попробовал сброс фабрики и возвращение в режим разработчика, но тем не менее ничто. Я думаю, что установщик, возможно, подошел прежде, но невольно я вышел из оболочки, таким образом, я думаю что, возможно, часть моей проблемы. Какие-либо идеи?
