Please let me know what target hardware are you using?
There are two session to download in SDK manager windows.
Which session did you try to access?
If NVONLINE session, please try to access in DEVZONE session.
If can’t log in via DEVZONE, please let me know. Thanks.
I restall my ubuntu 16.04,and download a new SDKmanager,but the result was the same, I can download the software like several days before,so maybe it is the account question,could please check the database please
Dear pengxiaoyu,
I assume you have removed cache(deleted ~/.nvsdkm folder) and tried installing with the latest downloaded SDKmanager. If so, Could you please attach latest logs now.
