  • You've a problem on your network configuration. It's not a problem with update-upgrqde. All your repositories try to connect to a local IP. Try to configure it.

You have misconfigured your proxy.

Go to Configuration -> Network -> Proxy settings. Change the actual value ( Automatic or to "Direct connection to Internet"

Save new settings and restart network from terminal with the command :

sudo service network-manager restart

Try apt-get update again


follow the steps below to fix it :-

Open /etc/apt/sources.list file.

Check the word after http://security.ubuntu.com/ubuntu/ in the sources.list file, let the word be xyz .. Go to the address http://security.ubuntu.com/ubuntu/ and then click on dists.

Now check whether xyz is present at this path. If it is not present, then replace xyz with the element which is present in 'dists' such as:- saucy, lucid, trusty etc.Now run 

sudo apt-get update
