андроид umake проксирует ошибку

Когда я работаю в Ubuntu 16.10:

$ umake android --accept-license
ERROR: https://developer.android.com/sdk/index.html couldn't finish download: HTTPSConnectionPool(host='developer.android.com', port=443): Max retries exceeded with url: /sdk/index.html (Caused by ProxyError('Cannot connect to proxy.', RemoteDisconnected('Remote end closed connection without response',)))
ERROR: An error occurred while downloading https://developer.android.com/sdk/index.html: HTTPSConnectionPool(host='developer.android.com', port=443): Max retries exceeded with url: /sdk/index.html (Caused by ProxyError('Cannot connect to proxy.', RemoteDisconnected('Remote end closed connection without response',)))

Это, кажется, проблема прокси, но у меня нет проблем с Кв. Как я могу установить значения прокси для umake?

Моя umake версия 16.05
