apt instructions not applicable on a new GCE VM

Debian 6.1.94-1 (2024-06-21) x86_64 GNU/Linux

Relevant session events:

$ sudo: add-apt-repository: command not found 
$ sudo apt install software-properties-common
$ sudo add-apt-repository ppa:alessandro-strada/ppa

AttributeError: 'NoneType' object has no attribute 'people'

To summarize:

• the poorly-named (not yer fault) command add-apt-repository is not present by default (hoping deprecation)
• when added from the default provided repo, the command gets a naked syntax error

BTW this looks like a good solution generally and I appreciate the work, thank you. Sorry it was a fail for me. Going to try circling a different drain now.
