MacBook Pro 13" 2017
MacOS Catalina 10.15.5
when running script, it won't find the ubuntu 18.04.4-amd64.iso image and the version and checksum are not updating dynamically, so it won't download 18.04.5 which is now available, nor it won't accept 18.04.5 renamed to 18.04.4 beacuse of wrong checksum.

Steps to reproduce:
1. Download http://tarballs.openstack.org/training-labs/dist/labs-master.tgz
2. extract and cd into labs
3. ./st.py -b cluster
Later I found out how it checks for "newer" image and already reported to Ubuntu CDimage that the md5sums file is missing the checksum for 18.04.5 images.
