Dear @wang_chen2,
There seems to be some issue with your network connection. I could download the cuda debian file on my machine. Do you need any network proxy to connect to internet/ download files ?

As @SivaRamaKrishnaNV mentioned, below is from your log. Can you access these deb packages from your host system?
