bionic amd64 choose-mirror still pointing to artful

[jeffrey leung]

I downloaded the latest live-server iso for Ubuntu 18.04 server amd64. I am trying to setup unattended PXE boot but running into an issue when trying to reach the remote mirror. I looked at the syslog and the choose-mirror package still seems to be trying to point to /dists/artful/Release instead of bionic:

May 2 00:01:05 choose-mirror[3603]: WARNING **: broken mirror: invalid Suite or Codename in Release file for artful
