Software Configuration is like this
Ubuntu 19.04 is out-dated. So all packages for Ubuntu 19.04 is found in old-release section.
This may cause this 404 error.
You can refer this post to solve error.

I am attaching screen shot as well.
What would be the reason ?
You have an issue with your DNS. I am sure that if you do:
$ ping deb.debian.org
You will also get an error.
I would recommend you to read this
