Report #99127

[bug\_fix] error: externally-managed-environment

Create and use a virtual environment \(python -m venv .venv\) and install into it, use pipx for CLI tools, or pass --break-system-packages only when you explicitly accept the risk. Do not pip install into the system interpreter on PEP 668 distributions.

Journey Context:
On Ubuntu 24.04 you run pip install flask and pip aborts with externally-managed-environment. The distribution marks its system Python as externally managed to protect OS packages from being broken by user installs. You create a venv, install flask there, and run the application from the activated environment.
