Do you need a proxy definition to access the internet?
Your configuration shows:

cat /etc/apt/apt.conf
Acquire::http::Proxy "http://172.16.8.1:8080/";

If you check the network configuration in your web browser - do you have the same proxy entry there?
One potential problem is that in case you need username and password for usign the proxy, you have to put these values into he configuration files (there is no option for asking these values form the therminal in the moment when needed).

I don't remember placing any such "Proxy Definition' explicitly !

Do I need to remove it?

Firefox Configuration says 'Use System Proxy Settings'

Yes, ISP requires me to provide username and password when I open browser for the first time, but this apt-get problem never appeared earlier (for the last 6 months)

You could try without the proxy definition in apt.conf

open a terminal and issue these commands:

sudo mv /etc/apt/apt.conf /etc/apt/apt.conf.bck
sudo apt-get update

copy/paste all output into theis question document as done before.

WHat is the output of:

egrep -i 'http|ftp' ~/.bashrc
egrep -i 'http|ftp' /etc/environment
cat /etc/apt/apt.conf

Thanks

This question was expired because it remained in the 'Needs information' state without activity for the last 15 days.

I'm sorry !

I solved the problem with the hint from Comment #7.

I apologize for my delayed response.
