# title : python39-fubar-20240804.txt
# author: Neil Rieck
# edit : 2024-08-04
# notes :
# 1) for the past 2 years, our CentOS7 system hosted 3 python flavors:
# python2.7 -built-in in to support OS utilities like yum + firewall-cmd
# python3.6.8 -installed from an EL7 repo
# python3.9.13 -built from source code since not available from the repo7;
so installed outside of yum and rpm
# 2) last month I used ELevate-leapp to migrate this system to AlmaLinux8:
# python2.7 -was not removed; but you can remove it whenever you wish
# python3.6.8 -now considered the base-python for supporting yum etc.
# python3.9.13 -was not touched (but was not updated to python3.9.19 since
# AlmaLinux8 does not know about it)
# 3) I tried using yum/dnf to install python3.9.19 overtop of python3.9.13 but
# that failed spectacularly which required a manual removal. Read on...
