Run this command below on your server and it will replace all of the  archive.ubuntu.com  and  security.ubuntu.com package repository URLs with  old-releases.ubuntu.com

sudo sed -i -e 's/archive.ubuntu.com\|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list

You may also want to see if there are other files in  /etc/apt/sources.list.d/  that need to be updated, which can be done with a simple grep command:


grep -E 'archive.ubuntu.com|security.ubuntu.com' /etc/apt/sources.list.d/*
