What are you seeing

Error: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install python' returned 100: Reading package lists...

Package python is not available, but is referred to by another package.                                                                                                                     
This may mean that the package is missing, has been obsoleted, or                                                                                                                           
is only available from another source                                                                                                                                                       
However the following packages replace it:                                                                                                                                                  
  2to3 python-is-python3     

What behaviour did you expect instead

Python should be installed (possibly via apt install python-is-python-3)

Hello, I just ran into this problem when working on an ubuntu24 host.

The 'version => system' directive seems to be misdocumented and may not be necessary on Ubuntu24. The following worked for me:

class profile::python {
  class { 'python':
    pip => present,
    dev => present,
  }
}

What solution did you use to this problem?
