It looks like the apt repositories for ubuntu 23.10 are no longer available. Indeed, I don't see mantic here:
http://archive.ubuntu.com/ubuntu/dists/
http://security.ubuntu.com/ubuntu/dists/

The latest 23.10 Docker image was pushed 6 months ago: https://hub.docker.com/_/ubuntu/tags?name=23.10

I guess the apt repositories are no longer available because the release is not supported anymore: https://endoflife.date/ubuntu

We should upgrade to 24.04 (LTS), just like @Abdul-Muqadim-Arbisoft did in main: see PR and issue #25.
