# TEMPORARILY USE pip3 to install the latest ansible-core as listed at

#apt install python3-pymysql python3-psycopg2 python3-passlib python3-pip python3-setuptools python3-packaging python3-venv virtualenv

#pip3 install --upgrade ansible-core # Then start a new shell, so /usr/local/bin works
|
|
#ansible-galaxy collection install -r collections.yml
|
|
|

# TEMPORARILY USE ansible-base 2.10.16 (REMOVE W/ "pip3 uninstall ansible-base")
|
|
#apt install python3-pip
|
|
#pip3 install ansible-base==2.10.16 # Start new shell, so /usr/local/bin works
