Greetings

I was trying to clean up my /usr/bin directory so was discarding older
versions of software.
Had python3.10 available so thought (foolishly - - now clear) that
python3.9 was a great candidate for discard.
Nope nix and no way.

Now I have myself more than a bit of a mess with my installed python systems.

Suggestions as to how to repair my 'mess'?

(Following is what the apt update upgrade process barfs up.
Please - - - I'm not any kind of programmer just an over eager user
who tends to beat his systems up - - - hard!!)
