scripts/ansible: Evaluate 'apt install ansible-core' on "32-bit" RasPiOS 12 Bookworm

[holta]

Possible replacement for PR #3632 if @EMG70 has time to try this approach?

(NOT elegant... basically forcing the install of old & overweight ansible-core 2.14.3... but might be easier than fighting "endless dependency hell" !)

Related:

• question: why does ansible need version 2.11.12 ? #3501
• Strange switch to 64bit kernel on 32bit RasPiOS [on 64-bit CPU architectures] #3516

Progress, at least this PR worked for @EMG70 on "fully 32-bit" RasPiOS 12 👍

And then separately, KA Lite failed to install (lacking Python 2?) as follows... [ also posted as new issue #3635 ]

So https://github.com/iiab/iiab/blob/master/scripts/install_python2.sh probably needs a bit of tuning in coming weeks, now that 32-bit RasPiOS 12 is about to be released.

FYI

• The if statement should probably be refined to exclude 32-bit RasPiOS 11 (Bullseye) as apt package ansible-core is not available on this legacy OS
• Or 32-bit RasPiOS 11 support can be deprecated entirely, as will be happening regardless rather soon in coming weeks, just as with PR local_facts.fact: Deprecate support for EOL'd Ubuntu 22.10 (Kinetic Kudu) #3621

[holta]

Above preliminary diagnosis clarified in the link below — to explain that Python 2 is probably not actually MISSING — but rather not being found by Ansible:

• KA Lite fails to install on 32-bit RasPiOS 12 Bookworm: Python 2 installed but not usable? ("failed to find interpreter for Builtin discover of python_spec='python2.7'") #3635

The if statement should probably be refined to exclude 32-bit RasPiOS 11 (Bullseye) as apt package ansible-core is not available on this legacy OS

Done!
