I am sorry to hear that the above command cannot achieve my promising results.
The I just find some clues that told me that the above problem is related about the proxy problem. Therefore, I just found this site.
sudo touch /etc/apt/apt.conf.d/proxy.conf
sudo vim /etc/apt/apt.conf.d/proxy.conf
Then just write the following content into the above file created recently.
Acquire {
HTTP::proxy "http://127.0.0.1:8080";
HTTPS::proxy "http://127.0.0.1:8080";
}
