Quando eu corro no 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',)))
Parece ser um problema de proxy, mas não tenho problemas com o apt. Como posso definir os valores de proxy para umake?
Minha versão de umake é 16.05
