Не удалось установить Ubuntu SDK после обновления 15,04 от 14,04

Я недавно обновил от 14,04 до 15,04, таким образом, я мог начать работать над идеей объема, что я имел. До обновления я установил SDK Ubuntu и установил его и частично работающий - но у меня были проблемы с эмуляторами и компиляцией.

Было предложено мне, чтобы я обновил до 15,04, и я уже планировал сделать так, таким образом, я обновил до 14,10 до 15,04.

Однако по пути SDK был удален. Я полагал, что это было просто нормальной частью процесса обновления, я могу просто переустановить его, когда я добираюсь до 15,04.

Неправильно.

Когда я работаю sudo apt-get install ubuntu-sdk команда, я получаю этот вывод:

$ sudo apt-get install ubuntu-sdk

Я попытался добавить ubuntu-sdk-team PPA через sudo add-apt-repository ppa:ubuntu-sdk-team/ppa, но это дает мне ту же ошибку.
