I seem like your apt repository is not having some issue.

Please check sources.list using the following command sudo vim /etc/apt/sources.list

I this some url's were missed in that file.

Here I'm providing new sources.list file for ubuntu 18.04 LTS. Back up your old sources.list file and replace the contents in the in below link:

Now do sudo apt-get update Hope this helps

If you're behind a proxy, do the following

sudo vi /etc/apt/apt.conf.d/proxy.conf

Define a http: and a https: proxy

Acquire::http::Proxy "http://user:password@proxy.server:port/";

Acquire::https::Proxy "https://user:password@proxy.server:port/";

Usually, there's no username when using a LAN-based proxy, so in that case you can just type the IP/hostname i.e

"http://192.168.1.10:3128/";

and same for the https counterpart

"https://192.168.1.10:3128/";

Run apt update to see if the error is gone.

I am using ubuntu 18.04.I got this error when i try to upgrade
