Kubuntu 19.04

Hello. I have been trying to make a custom dist iso using Kubuntu 19.04. Everything goes good until it tries to make the iso. It makes a 34KB iso file. It also gives apt some issues after I installed the latest version from github, because it requires an older version of a dependancy (i think it was some sort of vte python dep). Is there anything I can do to create a properly sized ISO of my 19.04 distro?

Thanks In Advance
