Change source.list to China user when re-install with SDK manager

sudo cp /etc/apt/source.list /etc/apt/source.list.bak

replace below in your /etc/apt/source.list
then start the sdk post install for cuda/opencv/deepstream etc.

Hi kassey,

Changing source.list file is risky, user could change to other source.list manually depending on their actual environment. We will keep current implementation as is.
