I generally use proxy for getting internet. Say proxy is xxx.xx.x.x.
But if the proxy is down, I select none and apply to system wide as shown below
After selecting none also, if I check for echo "$http_proxy" or echo "$https_proxy". the output is my old proxy address xxx.xx.x.x.
I checked in /etc/environment and .bashrc for any proxy export statements but none are there. Why proxy is still active?
Where I have to change, so that the system won't consider proxy that I use generally?
