Manfred Hampl (m-hampl) said : #1

Do you use a proxy server for accessing the internet? There might be a problem with it, or there might be a wrong configuration on your system that it tries using a proxy server that does not exist (any more).

Please follow steps 1 to 6 in https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure

and in step 6 paste all output into this question document that you have already created https://answers.launchpad.net/ubuntu/+source/update-manager/+question/267062

Also try:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

Then retry

aditya@aditya-Aspire-E5-571G:~$ sudo grep -R proxy /etc/apt/*
[sudo] password for aditya:
aditya@aditya-Aspire-E5-571G:~$ grep proxy /etc/environment

hi Manfred Hampl (m-hampl)

I kept the output in the comment and also in the question

Best Manfred Hampl (m-hampl) said : #5

Are you using a proxy server to access the internet?

Try the commands

cat /etc/apt/apt.conf
sudo rm /etc/apt/apt.conf
sudo apt-get update

and copy/paste all output as new response in this question document.

Try rebooting your router as well. It is a computer just like the one you are looking at. Can help to reset them from time to time.

Thanks Manfred Hampl, that solved my question.
