[21:56] <realtime-neil> within the ubuntu installer (specifically this one: https://releases.ubuntu.com/bionic/ubuntu-18.04.5-live-server-amd64.iso), where is the apt `sources.list` file that references the on-medium apt repository? I can see the `pool` and `dists` directories at the top of the installer contents, but where is the thing that refers to them?
[21:57] <realtime-neil> sorry, I meant this installer image: https://cdimage.ubuntu.com/ubuntu/releases/bionic/release/ubuntu-18.04.5-server-amd64.iso
