Неизвестное имя пользователя "whoopsie" после обновления до Ubuntu 14.04

После установки обновления до Ubuntu 14.04 LTS из Ubuntu 12.04. Я попытался завершить обновление, зайдя в оболочку после перезагрузки компьютера и набрав sudo sh -e ~/Downloads/crouton -n precise -u, Это было успешно, но когда я пытался sudo startunity сказано unknown username whoopsie in message bus configuration file, Я не уверен, что делать или какие команды использовать. Любая помощь отличная, спасибо!

Это именно то, что он сказал мне:
