 Ignore the fact I forgot to add instructions like `install`, `update`, or `remove`. I haven't used `pip` in a while, okay?
+## Why?
+```
+error: externally-managed-environment
+
+× This environment is externally managed
+╰─> To install Python packages system-wide, try apt install
+    python3-xyz, where xyz is the package you are trying to
+    install.
+    
+    If you wish to install a non-Debian-packaged Python package,
+    create a virtual environment using python3 -m venv path/to/venv.
+    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
+    sure you have python3-full installed.
+    
+    If you wish to install a non-Debian packaged Python application,
+    it may be easiest to use pipx install xyz, which will manage a
+    virtual environment for you. Make sure you have pipx installed.
+    
+    See /usr/share/doc/python3.13/README.venv for more information.
+
+note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
+hint: See PEP 668 for the detailed specification.
