Hello,

I can confirm your changes are working here:

  $ python3.9 -m ensurepip
  Looking in links: /tmp/tmp27uix56t
  Requirement already satisfied: setuptools in /usr/lib/python3.9/site-packages (80.9.0)
  Requirement already satisfied: pip in /usr/lib/python3.9/site-packages (26.0.1)

  $ python3.9 -m venv venv3.9
  $ ls ~/venv3.9/bin/
  activate  activate.csh  activate.fish  Activate.ps1  easy_install  easy_install-3.9  pip  pip3  pip3.9  python  python3  python3.9.exe

  $ python3.12 -m ensurepip
  Looking in links: /tmp/tmpxzfy0fpp
  Requirement already satisfied: pip in /usr/lib/python3.12/site-packages (26.0.1)

  $ python3.12 -m venv venv3.12
  $ ls ~/venv3.12/bin/
  activate  activate.csh  activate.fish  Activate.ps1  pip  pip3  pip3.12  python  python3  python3.12

Many thanks and regards
