sudo apt-get update failed me repeatedly

Question

I keep getting this output when I run sudo apt-get update:

Err:1 http://security.ubuntu.com/ubuntu xenial-security InRelease

How this problem can be fixed?

Try edit your sources.list
and change with

deb http://et.archive.ubuntu.com/ubuntu xenial main inRelease
deb http://et.archive.ubuntu.com/ubuntu xenial-updates main inRelease
deb http://et.archive.ubuntu.com/ubuntu xenial-backports main inRelease
deb http://et.archive.ubuntu.com/ubuntu xenial-security main inRelease

and try again

sudo apt-get update && sudo apt-get upgrade
