Thanks.
I had the same problem. I solved in this way:
sudo sed -i -e 's/archive.ubuntu.com\|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
grep -E 'archive.ubuntu.com|security.ubuntu.com' /etc/apt/sources.list.d/*
sudo apt-get update
You need to update your repository targets to the Eoan Ermine (19.10) release of Ubuntu. This can be done like so:
sudo sed -i -e 's|disco|eoan|g' /etc/apt/sources.list
sudo apt update

Cofession: I am just a noobie with shell and networking so sorry if this is some sort of blunder!
apt-get doesnt seem to work in my shell. It seems to be trying to connect to an IP (10.6.1.57) which doesnt even respond to a ping.
This is what happens when i try apt-update:

Check this file too: /etc/apt/apt.conf.d/00apt-cacher-proxy maybe there is some proxy as it was in my case.
Check in /etc/apt/sources.list.d/ for list files containing that ip.
I only changed one thing to get it working. Added "nameserver 8.8.8.8" to /etc/resolve.conf and it worked good
That can be both custom repository address and APT proxy override configuration. They can be set in several locations under /etc/apt/.
Resolve address 10.6.1.57 into host name (e.g. with host 10.6.1.57) and then search for both IP and host name in the whole /etc/apt/ directory.
grep -r 10.6.1.57 /etc/apt/
In my case it was custom Acquire::http::Proxy setting in /etc/apt/apt.conf.
